One Direction

One day Louis Tomlinson is changing diapers, the next he's sippin' Pacifico and taking off his girlfriend's bikini top in the Mexican sunshine.

Louis took a break from dad duties with 4-month-old Freddie for a vacay with girlfriend Danielle Campbell, who needed his help getting rid of her tan lines.

Liam Payne's shaking off his boy band roots by hooking up with Wiz Khalifa and Juicy J ... and the result is way more Timberlake and Jay Z than anything One Direction ever did.

TMZ's obtained the new track called, "You" -- one of 5 Liam's laid down with producer TM88 (from 808 Mafia) and Juicy J -- and you'll hear the 1Der singing the hook.

As we reported back in January, Liam's got flow too ... we're told you'll hear him rapping, as well as singing, when his solo album drops.

Sorry, One Direction fans ... we're shutting down your #Babygate fake baby conspiracy once and for all.

We got Louis Tomlinson out to lunch Thursday in Calabasas, and the pics prove his 2-and-a-half month old son Freddie is a living, breathing little tyke -- and not just a prop.

This has become a thing -- 1D fans are flooding social media with various #babygate conspiracy theories as to why the baby can't be real. They think Louis and his team are photoshopping images and using dolls to fake out the public.

So, here's Exhibit A -- watch and LISTEN to baby Freddie crying out. THIS is a real baby.

Case closed.

One Direction got Sony so excited the music company paid a wad of cash for the rights to one of their hits ... problem is, Sony sent the check to the wrong company and they won't give it back!

Here's the low down, which is hysterical to everyone but Sony. It licensed the 1D hit, "C'mon, C'mon," along with 2 other songs, for $65k. The company that owns the rights to the song is called Family Affair Productions.

Slight problem ... Sony claims it mistakenly sent the check to a company called Family Affair Music, which cashed it!

According to a new lawsuit, Sony claims it has been asking Family Affair Music for the money back, but it's fallen on deaf ears.

Louis Tomlinson turned heads while putting in quality time with his 2-month-old son because, let's face it, it's not everyday you see a One Direction member pushing around a stroller.

Louis pushed Freddie Thursday around the Calabasas Commons ... and made a stop at Barnes & Noble. Hopefully starting him off with the classics like "Goodnight Moon" or "Everyone Poops."

Naturally, we also recommend Sam Jackson's, "Go the F**k to Sleep."

Also ... warning to other boy banders: This could be you.

Use protection.

Louis Tomlinson and Briana Jungwirth have reached a shaky temporary settlement in their custody war ... avoiding a courtroom showdown by a matter of hours.

We've learned lawyers for the One Direction singer were going to court Friday morning armed with legal docs and their famous client, asking a judge to formally establish paternity on Louis' part and give him access to his 1-month-old son, Freddie.

TMZ broke the story ... Briana was not giving Louis access to their kid and the dispute was over money. We're told under the temporary settlement, he will have access to the child for several hours at a time during the week, but he will not have any overnight visits.

We're told until a short time ago, Louis was paying Briana's expenses but there was no set amount -- it varied from week to week. Things went south when they tried to establish a set monthly amount ... she wanted way more than he was willing to give.

Our sources say the 2 parents have agreed to a temporary custody arrangement while their lawyers hammer out something formal ... both with custody and child support.

Louis Tomlinson has lawyered up to wage a custody war, because he says his baby mama is not letting him see their kid ... TMZ has learned.

Sources connected with Louis tell TMZ, the One Direction singer claims Briana Jungwirth has gotten greedy and wants money ... and lots of it. He claims she's using their 1-month-old son, Freddie Reign, to leverage a bigger payday.

It's a surprising turn ... Louis got Briana a 3 bedroom home in Calabasas and he's renting a $21 million home in L.A. to be close to Freddie.

Louis has not gotten a DNA test but says there's no doubt he's the dad ... they dated exclusively during the period in which she got pregnant.

We're told Louis is gunning for an order forcing Briana to give him some custodial rights, including significant access to his son.

Louis Tomlinson tossed bro code out the window by hitting the town with his old One Direction mate Zayn Malik's ex fiancee.

Louis and Perrie Edwards were spotted Wednesday night taking a car together after the Brit Awards. Perrie and Zayn broke things off in August -- about 5 months after he left the group.

Last night could've just been a convenient carpool sitch though, since Louis has been tight with actress Danielle Campbell lately.

Besides, even Paul McCartney and Yoko Ono see each other from time to time.

Look it up, 1Ders. It's relevant.

Louis Tomlinson is so sure newborn son Freddie Reign is his kid, he has no plans to prove it with a DNA test ... TMZ has learned.

Sources close to Louis and Briana Jungwirth tell us the 1D-er's always copped to the kid being his ever since finding out Briana was pregnant. They started dating about a year ago and we're told things were so serious initially, he had zero doubt Briana was faithful.

While any lawyer would tell Tomlinson to seal the deal with a paternity test ... we're told he's totally cool with passing.

Louis Tomlinson is so serious about being a hands-on father, he's moving into a $21 million L.A. home to be closer to his newborn son.

The pad will be more fun for Louis than it is for baby Freddie, since it's got a home theater, gym, pool, insane city views ... and Leonardo DiCaprio as a neighbor.

The 1D star scored the sweet rental from celeb hypnotist Paul McKenna because he wants to actively co-parent with baby mama Briana Jungwirth.

As we reported, Tomlinson did right by Briana, and rented her a decent pad in Calabasas.

Louis Tomlinson's 1-week-old son doesn't have to worry about his name being pimped out on the Internet, thanks to his mom's family.

Briana Jungwirth's family registered FreddieTomlinson.com on January 27th ... minutes after Louis and Briana first revealed baby Freddie to the world.

Sources close to the couple tell us once the baby's name was revealed, One Direction fans started creating bogus social media accounts with Freddie's name, and pretended to be associated with the family.

We're told Briana's family wanted to protect the kid's best interests and block any squatters -- after all, he is 1D royalty. Baby Freddie's now free to focus on important things like pooping and breastfeeding.

Not necessarily in that order.

Louis Tomlinson's newborn son's name was the first adventure in co-parenting for him and baby mama Briana Jungwirth.

As we've reported, the kid's name is Freddie Reign Tomlinson and our One Direction source tells us Louis picked out the Freddie part, while Briana came up with the royal-sounding middle name.

No rhyme or reason for Freddie, we're told Louis just liked the ring of it and Briana didn't object.

As for Reign, we're told Briana wanted something earthy, but thought Rain sounded too girly ... so she went with the more kingly version.

It's all fun and baby names -- until diaper duty starts.

Here ya go One Direction fans -- Louis Tomlinson taking the stage for the first time ... as a hands-on dad!

Louis loaded up his newborn son into an SUV, along with baby mama Briana Jungwirth. Looks like daddy Louis had first shift on car seat duty as they headed to the hospital for a checkup.

Their kid's about 6 days old ... but Louis and Briana still haven't announced a name. Tuesday's outing was the first time the new parents have been seen together in months.

Louis Tomlinson is providing for his baby and baby mama, but the digs are modest and the jury is out on child support.

We've learned Briana Jungwirth and their son are living in a 3 bedroom home in Calabasas ... a far cry from the reported $10 million mansion he reportedly bought her. We're told the home is in the hundreds of thousands of dollars ... not in the millions.

We're told Briana is paying for the furniture and Louis isn't exactly opening the bank vault.

Louis is renting his own place in L.A. so he can be closer to his son. We're told it's a lot nicer than Briana's digs.

The new parents are getting along, but they have not settled on a child support figure yet. There are reports she wants $600k a year. That may well be in the universe of possibilities, but a lot depends on his income and the needs of the child ... that's the way it's done in California.

Briana is telling her friends she's not using the baby as a meal ticket ... getting help is fine, but she insists she won't get greedy.

Louis Tomlinson did NOT miss the birth of his first child ... TMZ has learned.

Our sources say the One Direction singer was at the L.A. area hospital when ex-gf Briana Jungwirth popped out their son on Thursday evening.

Louis was out in Beverly Hills Friday, making a quick stop at a sunglasses shop -- 'cause, really ... what's cuter than a baby in shades? The photog asked about a possible baby name, but Louis played it coy.

Briana's doing well and still at the hospital with the baby. We're told she's seen all the fake baby pics posted by 1D fans today, but rest assured ... they're all bogus.

Baby hasn't done any photoshoots. Yet.

There's a new generation of One Direction ... Louis Tomlinson and his former GF have a baby boy.

Briana Jungwirth gave birth this week in L.A. It's the first child for both of them -- Louis is 24 and Briana's 23 -- and the first kid for any of the 1Ders. No word on a name yet.

It's unclear if Louis was in town for the birth. He and Briana only dated briefly before she got pregnant, but we're told they've gotten much closer during the pregnancy ... especially after Louis made a special trip to L.A. to hang with her family over the summer.

Mazel tov!
