Ben Affleck and GF House Hunting!!!

Ben Affleck was house hunting ... no big surprise since he's apparently in the market after moving out of the family home, but what's interesting is that he brought his girlfriend along for the ride.

Ben and Lindsay Shookus were all over the west side of L.A. Tuesday ... looking at super expensive homes. One house in the Santa Monica mountains is listed at $18.5 million, another in Pacific Palisades is going for $12 million and one in Brentwood is also on the market for $12 mil.

They also looked at a house under construction, and they walked the property.

It seems they were smitten by the Santa Monica mountains house because they stayed for more than an hour. Lindsay was clutching the spec sheet as they left.

No word on whether Ben's moving in alone.

Kim Kardashian My Disney Birthday Is a Scream

Hard to tell who enjoyed Kim Kardashian's birthday party more -- Kim or her kids, since they all let loose in a big way all over Disneyland.

Kim's entourage -- North, Saint, Aunt Kourtney, Larsa Pippen and their kids -- roamed the Anaheim park on Tuesday ... complete with VIP tour guides and bodyguards, of course. The triple digit temps didn't seem to bother the krew.

She's 37 now, but Kim looked more like a carefree 7-year-old while riding Dumbo, the Gadget's GO Coaster and the Monsters Inc. ride.

And yes, she recreated that classic churro shot. It's her birthday ... but we can all be happy.

WWE Superstar Lana Strips Down to Bikini In Crazy L.A. Heatwave

How do you stay cool when the temp's over 100 degrees? Bikini beach day!!

That's what WWE superstar Lana did while the rest of the city was melting.

Lana was rollin' solo in Santa Monica -- no sign of her husband, Rusev ... but we're not complaining.

The model/reality star/singer -- real name CJ Perry -- is also an actress and appeared as one of the Bellas in "Pitch Perfect" and "Pitch Perfect 2."

By the way, the weather in L.A. is expected to be hot as hell the rest of the week -- so ... good for us!

Fats Domino Dead at 89

7:50 AM PT -- Jefferson Parish Coroner's Office tells TMZ Fats died of natural causes and his body was released to a funeral home. There was no autopsy.

Fats Domino, the legendary New Orleans singer and piano player who took the '50s and '60s by storm ... is dead.

Domino died in New Orleans, surrounded by friends and family, according to his daughter.

His hits were epic ... "Blueberry Hill," "Ain't That a Shame" and "I'm Walkin'."

Domino sold more than 65 million albums, and received a Grammy Lifetime Achievement Award in 1987. He was inducted into the Rock & Roll Hall of Fame in 1986.

He was deeply embedded in New Orleans, and did a lot of public appearances for relief efforts after Hurricane Katrina.

Domino was 89 years old.

RIP

Serena Williams Serves Up $12 Mil Bel-Air Pad

Serena Williams is looking to double up on the massive Bel-Air mansion she bought for $6 mil in 2006 -- 'cause it's now on the market with a $12 mil price tag.

Unclear why Serena is unloading the property -- it's really cool, located in a really nice area and it's HUGE.

The home is 6,101 square-feet and looks like a palace -- with 6 beds, 7 baths -- and has a grassy area that spans roughly 2.7 acres and includes private hiking trails ('cause who's got time for L.A. traffic?).

The big surprise -- no tennis court!

So, where is Serena going? She's got multiple properties in Florida and her fiance Alexis Ohanian has a spot in NorCal ... so she's got options.

Justin Bieber Bev Hills Bachelor Pad Runs $55k/Mo

Justin Bieber can't be thrilled about an alleged trespasser on his property -- but he's gotta be stoked about the crib itself, 'cause it's a bachelor's paradise.

TMZ has learned Justin's renting the Bev Hills house where an unwelcome intruder has shown up over the past week. He's spending a whopping $55k/month, and one look around the place explains why he'd fork out that kinda dough.

It's got 6 beds, 5.5 baths and over 8,600 sq. ft. -- way more house than a single guy like Bieber needs. Not to mention it also has a movie theater, gym, home office, pool and spa, and a fire pit. We're told the pad was rented through You Me Him and Her Rental Properties and CIRG Brokerage Inc & LA Estate Rentals.

Oh, and the bathrooms come with their own TVs, or at least the one where JB took this pic does.

We broke the story ... a woman was arrested Monday after cops say she was trespassing on Bieber's property, for the third time this week.

Our suggestion ... up the security, and park it. This house is too good to leave.

David Beckham Bae Watch Anyone?!

David Beckham's beach bod is unlike any dad bod you've ever seen ... you're welcome.

The 42-year-old -- cool dad status in full effect -- hit up Malibu Sunday with a bunch of his kids to cool off after a blistering weekend in Los Angeles. A little boogie boarding did the trick to cool the brood in the ocean.

Perhaps the only disturbing thing we see in this family outing -- using a beach volleyball as a futbol.

Give the former soccer prince a pass.

What's The Big Frigin' Difference?!

Don't get too worked up looking at these almost identical images of Billy Ray and Miley Cyrus -- embrace the challenge and see if you can spot the differences between these two super similar shots.

**HINT -- There are THREE differences in the above photographs!**

Jennifer Lopez One Shade of Grey Is All This Booty Needs

There's no grey area when it come to Jennifer Lopez's best asset, which was on full display Friday in NYC ... in yoga pants.

J.Lo still had a glow to her leaving her SoHo gym, but you'd never notice it if her butt caught your eye first.

So what does J.Lo's workout include? If it ain't downward dog, we're guessing it's a ton of squats because that booty is only getting better with age.

Who's doing retirement better than A-Rod? Absolutely no one.

Kendall Jenner: Courtside for Blake Griffin!? ... Hell Yeah.

Kendall Jenner had the best seats in the house to support her man Blake Griffin on Thursday night -- sitting courtside as BG's Clippers beat up on the Lakers at Staples Center.

And to prove that supermodels really do eat ... she indulged on a giant caramel apple for all to see!

Kendall was just one of the many superstars in the arena -- Flea, Gal Gadot, Floyd Mayweather and, of course, Jack Nicholson were all on hand for Lonzo Ball's pro debut.

Oh, and check out this bonus pic we've unofficially titled, "Belly, Boobs, Billionaire."

Good times ...
