Drake Rock Hard ... For Serena?

Drake is taking this SWOLL patrol thing very seriously, especially in the arms department ... and it might have something to do with impressing his lady friend Serena Williams.

Champagne Papi hit the gym -- it was a curls-for-the-girls day ... and you gotta think all that upper body strength will come in handy on date night. Fact is, Serena's physique is world class -- so you'd expect Drizzy to step up his game too.

When Serena's the gain, you don't mind the pain.

Ashley Benson Letting Loose In Mexico Check Out My Bikini

The summer may be over but don't tell that to "Pretty Little Liars" star Ashley Benson who busted out her sexy bikini for her trip down to Mexico.

The Kiini two piece has been popular all summer, with Heidi Klum rockin' the same skimpy suit a couple months back.

No need to ask who won this battle of the bikinis ... we all win.

Katy Perry Why Isn't Anyone Staring ... At My Hands?

Katy Perry left her handprints outside the famed Chinese Theatre in Hollywood on Tuesday night -- not that anyone noticed.

Nice pair.

Female Body Builders Flossin' On Muscle Beach

A bunch of hardbodied female bodybuilders showed that Muscle Beach is as much about buns as it is guns ... glutin' it up all over Venice Beach, Ca for a Labor Day bikini body showdown.

The ladies strutted their stuff at the 7th annual Muscle Beach Championship and bikini competition this past Monday and from the looks of these pics ... it was a really cheeky competition.

Check out the pics ... as many times as you like. We won't judge you.

Kylie Jenner Tyga Marks My Spot

Kylie Jenner posed for famed photographer Terry Richardson while showing off a ton of cleavage ... and a conspicuously/perfectly placed stuffed tiger doll.

Kylie and Terry shot a spread and cover for the latest issue of Galore magazine. She also did an interview with the mag, and acknowledged ... "For me, age is just a number."

We'd say Tyga agrees.

Remember when smokin' hot model Lindsey Pelas invited J.J. Watt to "slide into my DMs?"

Well, when we saw Lindsey at the First Slice Media party over the weekend, she was certainly suggesting he took her up on the offer.

Check out the clip ... we also asked if there were any OTHER big athletes she's got a crush on -- but it's clear, it's J.J. or bust for Pelas.

Coco Unveils Bikini Bod ... Butt Trumps Bump

Coco finally showed off her pregnant body in one of her barely-there thong bikinis, but her baby bump was overshadowed by her trademark butt.

Mrs. Ice-T posted the pics -- then deleted them shortly thereafter -- saying, "For some reason many of you have been asking weeks now to see my baby bump in a swimsuit! And of course I had to do it, Coco style and rep in a micro bikini."

Coco gives a helpful hint to pregnant women ... if you're real toned, you don't show as much.

Heidi Klum Spanks a Lot ... For the Ass Shot

Heidi Klum's been a very, very bad girl, and the world is a better place for it.

Klum put up this pic of a bare ass getting spanked with something called "The Naughty Spoon." Impossible to say if those are Heidi's cheeks misbehaving in the shot -- but since she included the caption, "Ouch" ... we're gonna go ahead and assume it's her.

It's just hotter that way.

Ryan Phillippe Skin to Win ... For Fitness

A shirtless Ryan Phillippe jogging over the weekend in his Beverly Hills neighborhood could be proof the fountain of youth does in fact exist.

Phillippe -- and his 6-pack abs -- don't look like they've aged a bit since his "Cruel Intentions" and "54" days.

This is 40, folks. For Ryan.

Serena Williams Butt-A-Like Blowing Up ... After IG Shout-Out

MY STOCK IS RISING
TMZSports.com

There is money in Serena Williams' butt ... or in having one that looks exactly like it ... 'cause an L.A. model says that since Serena shouted her out as her official butt-a-like ... her phone has NOT stopped ringing.

The model's name is Olivia Griffian, and she tells TMZ Sports her life was changed after Serena posted a picture of the two standing back to back at a recent shoot with a caption that read, "Found my Doppelgänger which one is me?"

Olivia says after the post, her Instagram followers nearly doubled and she was inundated with calls from agents and managers wanting to rep her ... all because of her striking resemblance to Drake's boo.

It's no accident that she was body doubling for Williams ... she claims the two are friends and talk everyday ... but she never thought looking like her pal would be worth so much fame.

Check out the clip, and the gallery below ... she might actually give Serena a run for her money.

Rita Ora Star-Spangled Nipples

Rita Ora put her love for the good ole U.S. of A. on full display ... on her nipples.

Ora fell 48 stars short of a true American flag salute after her Wednesday night show at the El Rey Theater in L.A. -- though we doubt she heard a single complaint about it.

Perhaps next time ... Rita can take a few pasty pointers from Miley Cyrus, who definitely wore them better last night on "Jimmy Kimmel Live!"

They are a party in the U.S.A.

Karlie Redd I'm Choosing Playboy Over Porn

Karlie Redd is taking the high road when it comes to stripping for cameras, opting for Playboy instead of porn.

The ‘Love & Hip Hop: ATL’ star will be getting fully naked for Playboy Plus, the magazine’s NSFW sister site (act like you don’t know).

Karlie thinks the Playboy route is classier than the Vivid route ... the company offered her $25k for a sex tape, which she seriously considered but ultimately rejected.

Playboy Plus says they'll shoot Karlie next month and the pics will go public this fall. They plan on putting Karlie in the celebrity section where she'll be right at home with Kim Kardashian and Madonna.

J. Lo Right Jeans ... Wrong Block, Jenny

Maybe Jenny from the block just made a wrong turn -- but yeah, Jennifer Lopez shot her latest music video ... in Brooklyn.

Luckily, her famous Bronx booty still looks amazing ... any borough, city, country or universe will do. Especially in those genes jeans.

You're welcome, Brooklyn.
