Heidi Klum Bite My Buns, Hun

Heidi Klum's BF is a serious brown-noser -- and a lucky son of a bitch.

Klum and Vito Schnabel got very playful Thursday in St. Barts, where he was happily -- we're sure -- behind her efforts to get up on a surfboard.

Check out the pics ... Vito caught a few waves, but Heidi was satisfied sunning her buns on the board ... which seemed just peachy to him.

Michael Strahan Still Sack Champ ... Takes Down Bikini Bae in Waves

Michael Strahan is feeling mighty young today ... if it's true you're only as old as the women you feel.

The 44-year-old star of 'Kelly and Michael' was all over his 28-year-old gf Kayla Quick during their vacay on St. Barts. The couple showed off their hard bodies on the beach, and played what looks like a game of tag in the water. Clearly, they both won.

Check out the pics ... beats the hell out of sacking quarterbacks, right Mike?

'Smallville' Star This Ass Fears No Kryptonite

Laura Vandervoort, who played Supergirl on "Smallville," had to channel some of her own super strength when wrestling the ocean tide for her bikini bottom.

Vandervoort is on vacation in Cancun with her boyfriend. Doesn't seem like she's too upset about the near stripping. That's what vacation's for, right?

Gotta say ... she definitely looks better in a bikini than a cape.

Steven Tyler Livin' On The Edge Of A Lake ... In A $10k A Night Pad!!!

Steven Tyler hit up Walt Disney World over Easter weekend and while he didn't crash at Cinderella's Castle, the place where he did stay looked like its own mini Magic Kingdom.

TMZ has learned ... Airbnb hooked up the Aerosmith frontman in a $10k a night lake house in Windermere, about 20 minutes outside Orlando. In other words ... Steven paid zilch to stay there.

We're told he came with his family and there was more than enough room for everyone because the place is huge.

The 4-bedroom home has its own dock on Lake Butler for anyone that gets tired of swimming in the pad's lagoon-like pool.

No doubt Steven slept like a baby after riding the Aerosmith Rock 'n' Roller Coaster ... yep, that's a ride there.

Maria Sharapova Bikini Weekend w/ Chelsea Handler ... Tests Positive for Hotness

Now that she's got free time (thanks to that suspension) tennis superstar Maria Sharapova ran for the border this weekend ... spending her Easter in a bikini with Chelsea Handler.

The two were spotted in an exclusive area of Cabo San Lucas -- where they took in some sun, took out a boat ... and even rapped together.

The 28-year-old was provisionally banned from tennis after testing positive for the banned substance meldonium ... but it seems she's treating the whole thing more like a vacation than a punishment.

Ole!!!

David Letterman Joaquin Phoenix Is My Spirit Animal

David Letterman the late night host is no more -- replaced by someone who looks a lot more like Joaquin Phoenix from back in the day.

The 68-year-old already is getting more unrecognizable by the day. He's down in St. Barts sporting a new bald and even bushier bearded look.

If any ZZ Top cover bands are hiring in the Caribbean ... get Dave a guitar.

Jessica Alba Just the Way We Like Her!!!

Jessica Alba was up to her knees in hotness as she waded in the blue Pacific.

Jessica and hubby Cash Warren soaked up the sun in Hawaii. They've been together long enough that they're comfortable wearing matching fedoras.

There are shades of Watergate in these pic ... a sinister cover-up.

Adrienne Bailon I'm Born Again in Mexico!!!

The boyfriend first ... Israel Houghton is a famous Christian singer who's got 6 gospel Grammys. Adrienne appeared in the 2013 flick Israel produced called, "I'm in Love with a Church Girl."

Israel just recently became officially available, although he's been seeing Adrienne for a while. They began dating after he divorced his wife of 20 years earlier this year.

Krysten Ritter Ocean Jewel

Krysten Ritter is doing the New Avengers right in a bikini, especially from behind.

The "Jessica Jones" star enjoyed the surf in Cancun looking super hot.

Good news ... Ritter's Marvel series got greenlit for season 2. Bad news ... she was on vacay with her boyfriend, not Luke Cage (for all those "Jessica Jones" fans out there).

Julianne Hough More Ass ... More Fun

Julianne Hough got her last licks in a bikini down in Mexico ... gracias dios!

Julianne, her sisters and their mom practiced the time honored tradition of "Sun's out, buns out" on their final day of vacay in Cabo San Lucas.

The only thing sick this time around are their swimsuits -- way better than the puke fest that went down the other day.

When they got back to LAX, JH and co. had an explanation for that mess ... if you buy it.
