Here's Ethan Hawke at the Berlin Film Festival on Monday (left) -- and Sugar Ray lead singer Mark McGrath back in 1999 (right).

Reality bites.

It's only been one month since Mallory Hagan won the title of Miss America 2013 ... after KILLING IT in the swimsuit competition ... and it appears she's back to eating like a normal human being again.

24-year-old Hagan was spotted rocking a pink bikini in Hawaii yesterday ... still looking incredible ... with a little more to love.

Sometimes ya just gotta let loose.

Here's Miley Cyrus at JFK airport on Tuesday (left) -- and a blow-up doll (right).

They lip-synched.

Deena from "Jersey Shore" says she's NOT a Mardi Gras booby flasher -- and claims she's getting a bad rap thanks to a sluttier doppelganger who looks just like her.

TMZ obtained video of a girl -- who looks EXACTLY like Deena -- partying her face off, lifting up her shirt and flashing her boobs down in New Orleans this week ... and people who witnessed the event first hand were convinced they were observing authentic MTV tatas.

But the REAL Deena tells TMZ it's not what it seems ... explaining, "I'm in Jersey right now ... plus if I were down in Mardi Gras I would NOT be showing off my boobs or any of my goods."

She continues, "I've been trying to work on changing my image especially since I want to be casted on 'Dancing with the Stars.' I get imitation is a form of flattery but this is definitely not the imitation I can ever hope for."

Fine. No beads for you.

Turning 32 must really suck -- because yesterday in L.A., "Destiny's Child" singer Kelly Rowland could hardly keep it together after her birthday lunch with Beyonce and Jay-Z.

It was a battle of the super babes as Sports Illustrated cover girl Kate Upton and A.J. McCarron's overnight sensation GF Katherine Webb -- who also appears in the S.I. swimsuit issue -- brought their gorgeousness to David Letterman in NYC on Monday.

Question is ...

"Shahs of Sunset" star Mike Shouhed got a helping hand from his butt oiling assistant/girlfriend as he readied his hairless golden muscles for his Playgirl spread, Sunday in L.A..

While there's no official word if he is going to go full frontal or pull a Levi Johnston, with a strategically placed towel, the 34-year-old real estate stud did let most of it all hang out while prepping for the shoot.

Kate Upton's breasts -- and their owner -- are on the cover of the Sports Illustrated Swimsuit Edition for the second time ... proving good awesome things really do come in pairs.

Katy Perry's giant TA-TA's ... Alicia Keys' underboobs ... Kelly Rowland's twins ... turns out they were all given the stamp of approval from CBS -- despite the network's previously harsh warning to keep the nakedness to a minimum.

Despite these revealing outfits -- and several more -- a rep for CBS tells TMZ, "All wardrobe selections passed our standards, if only barely."

You'll remember … CBS issued a memo urging everyone in attendance to cover up or else -- saying in part: "Please be sure that buttocks and female breasts are adequately covered. Thong type costumes are problematic. Please avoid exposing bare fleshy under curves of the buttocks and buttock crack."

If this is the music biz covering up ... count us in!

For the good of all mankind, the gorgeous ladies did what they do best and poured all of their luscious golden lady bits into skimpy frilly lingerie -- and super high stiletto heels -- and struck some amazing poses.

With her beleaguered blonde weave in need of a tune up and rockin' some Whitesnake groupie heavy black eye makeup, a low cut animal print top from the Forever 21 sale rack, and a pair of badly dyed bleached out jeans last seen leaving a Bon Jovi concert in 1988, newly single Britney Spears made a much needed trip to a beauty salon in Westlake Village on Sunday.

Under the watchful eye of CBS censors, Rihanna kept her lovely girls barely covered in a blood red gown at the Grammy Awards on Sunday.

With no sign of poor Michelle Williams ... Beyonce and Kelly Rowland both made appearances on the Grammy Awards red carpet.

While Bey kept it movie night casual in pants, Kelly went all out in a body-baring gown.

The question is ...

Despite his injured hand from his recent fight with Chris Brown, Frank Ocean was all smiles at the Grammy Awards on Sunday.
