So on the same day Michelle Rounds filed for sole custody of the child she shares with ex Rosie O'Donnell, she hit the town with a smoking hot model. What are the odds????

Rounds was out Tuesday night at Madera Kitchen where she walked out with her arm around Carmen Ortega ... who once dated Reggie Bush and was also possibly maybe the reason Jason Derulo and Jordin Sparks split.

We can't say Rounds and Ortega are together. In fact, a rep for Ortega says they're just working on a clothing line together -- but Rounds still went out of her way to snuggle close to Ortega for the cameras to see.

Not that we can blame her.

It's been a while since we've seen 75-year-old Tina Turner out and about ... and after seeing how good she's looking these days, we gotta ask ... why the hell isn't she out more???

Turner emerged Tuesday on the streets of Milan for a shopping trip with hubby Erwin Bach.

Private dancing keeps you young.

Zac Efron and Robert De Niro are getting close ... very close ... while shooting "Dirty Grandpa" down in Georgia.

Zac Efron is a brief guy ... at least he was on the set of his new film "Dirty Grandpa."

Efron is filming down in Georgia on Tybee Island and Monday he appeared to be baring it all. No such luck, just nude colored undies.

Funny, we had him pegged as a boxer guy but we're pretty sure there's a lot of ladies (and guys) who don't mind undies this tight.

There is nothing in Harry Styles' life that isn't awesome -- super popular band, chicks throwing themselves at him, and tons of money to buy cool classic cars.

The One Direction heartthrob was out Monday in Beverly Hills, crusising in a white vintage Mercedes-Benz SL convertible.

Shia LaBeouf's got wood ... LOTS of it -- after hauling off huge loads of logs in L.A.

Looking like a hybrid of a hipster lumberjack and a smooth jazz DJ -- ponytailed Shia was doing some major wood work Monday ... hauling logs with TreePeople, an LA based non-profit environmental organization.

Hard to tell what Shia's up to now -- bizarre art installation, DIY home improvement project, or just charity ... honestly, we're stumped.

Hayden Panettiere's face during her man's boxing match at Madison Square Garden this weekend can be summed up in two words ... FINISH HIM!!!

Heavyweight champ Wladimir Klitschko defended his title against Bryant Jennings on Saturday night, and while he might have done most of the work ... you gotta give Hayden major support props ... just for her gold-trimmed blazer alone.

If the world didn't know it before, HP's not only riding the Wlad train ... she's also its whistle.

All aboard.

Nikki Reed's marital status has gone from married to divorced to married again in the blink of an eye ... after getting hitched this weekend to "Vampire Diaries" star Ian Somerhalder.

Reed and Somerhalder exchanged vows Sunday in Malibu, where guests included "Glee" star Lea Michele and her boyfriend Matthew Paetz.

Reed split from "American Idol" star Paul McDonald in March 2014 and began dating Somerhalder in July. They even did a short engagement ... she got the ring in January, now they're hitched in April.

Brad Pitt's face is indestructible -- a fact whoever (or whatever) hit Brad should have known before attempting to disfigure our national treasure.

Brad showed up for a charity event in Hollywood Saturday night with a big bruise that starts under his left eye, and trails under his nose.

Most people would've stayed home with that kind of scarring, but most people don't have BP's genes. No clue what's behind this crime against beauty -- we've got a call in to his rep.

Anna Chickadee Cardwell is pregnant ... but this time around grandma won't be in charge.

Chickadee tells TMZ, she and husband Michael are 6 weeks pregnant. If Mama June reads this it will be the first time she'll learn she's going to be a grandma 2 times over.

June was calling the shots after Anna's first baby, Kaitlyn, was born, but this time June will be allowed to visit when Anna's around, but that's it.

Anna says she doesn't trust her mom's judgment anymore, because when she was younger, June would leave her with various people for long periods of time. One of them was child molester Mark McDaniel.

Anna says the only men who she'll trust with the new baby will be her husband and Uncle Poodle.

But Anna knows the value of a buck ... she says that there's one thing Mama June will come in handy for ... diaper coupons.

The woman loves a good bargain.

Mark Wahlberg always has time to help a brother out -- whether it's Tom Brady, or the homeless guy who gets caught in a swarm of photogs -- and his generosity was on full display in Bev Hills.

After Mark and his entourage had lunch at E. Baldi on Thursday ... he was making his way to his ride when he handed a C-note to a guy in a wheelchair without missing a beat or making a big deal about it.

It's as smooth and solid a move as we've ever seen a celeb make.

Bonus: Mark sounds off about the QB of his beloved Patriots skipping the team's White House trip. His take -- heartwarming ... and a little cocky.

Wicked awesome.

Gigi Hadid does not know how birthdays work -- instead of receiving gifts, she's giving them ... in the form of a hot new swimsuit photo shoot. Yes, it's a happy birthday ... for us all!

Hadid celebrated her 20th on Thursday by posing for a bunch of photos in Miami and, thankfully ... changing into a bunch of colorful and revealing swimsuits in the process.

One Direction's Louis Tomlinson is easing back into bachelorhood ... by hooking up with multiple chicks at once -- or so it seemed when a pack of at least 3 went to his London hotel room.

Tomlinson was partying at Cirque Le Soir Wednesday night ... before the after-party moved to the Soho Hotel. Best part of the rendezvous -- the girls' walk of shame Thursday morning -- although maybe it's more like walk of fame ... when you've raged with a One Direction singer all night?

Tomlinson broke up with GF Eleanor Calder last month after 4 years together.

Everyone mourns in their own way.

L.A. County Sheriff's deputies paid a visit to Bruce Jenner's Malibu house Tuesday ... then went on the hunt for the paparazzi who have been perched on a nearby hillside and taking aim with telephoto lenses.

It's illegal for photogs to use telephoto lenses to invade the private spaces of the people they're shooting.

The photographers took pics of Jenner earlier in the day that were being peddled around town. They've also taken pics over the last week from the same perch and Bruce has confronted them. He said he would call the cops if they came back. Tuesday Bruce made good on his promise.

Wladimir Klitschko may be the heavyweight champion of the world, but he's about to get his ass kicked by his 5' fiancee.

Wlad took baby Kaya out into the Miami beach surf, while Hayden Panettiere was doing 'GMA' in NYC.

It looks like fun and games, but we're guessing Hayden will have issues:

-- the baby doesn't have a life jacket

-- Wlad is clowning off balance in the surf, with Kaya in a precarious position

-- she's not wearing a hat in the Miami sun

That said, dad is no ordinary father at 6'6" and 246 lbs. Kaya's in good hands. Of course, Hayden might not see it that way.

Good luck Wlad ... we're rooting for you!.

Here's Lindsey Vonn, Olympic gold medal skier and girlfriend of Tiger Woods, appearing Monday on "Late Night with Seth Meyers" -- and Tiger's ex-wife, Elin Nordegren, seen a few years back strolling on Miami Beach.

The question is ...
