Fashion

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 ...

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.

Forget Super Bowl rings ... New York Giants star David Diehl just earned some new hardware -- a SCRAM bracelet ... after pleading guilty to DUI ... TMZ has learned.

As we reported, Diehl was busted last June in Queens after he crashed into a parked car -- and according to the D.A. his blood alcohol level was .182 ... more than twice the legal limit in New York.

Diehl pled guilty today to aggravated DUI and impaired driving.

Diehl was ordered to wear a SCRAM bracelet -- to monitor his alcohol consumption -- for 90 days and was placed on a 6-month conditional discharge program ... meaning he'll avoid jail if he keeps his nose clean.

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.

The CBS censors can rest, porn diva Jenna Jameson -- with her blonde Miley/P!nk weave -- kept all of her XXX lady bits covered in a demure gold foil gown at the Grammy Awards on Sunday.

While there's no word why the hell she's at the Grammys, Jenna is known for her amazing oral skills.

CBS fashion censorship memos be damned, her highness Jennifer Lopez showed up to the Grammys with a very high cut gown that showed off her gorgeous Jolie leg and then some.

Doing her best Mrs. Roper impersonation, Adele looked gorgeous in a red floral tapestry at the Grammys on Sunday.

At least it's different from her usual shapeless black ensembles, right?

Fresh from wrecking his car yesterday, Chris Brown showed up the Grammys -- without Rihanna at his side -- and proved he's got a lot of nerve ... to wear an all white suit.

Looking dapper as usual, Justin Timberlake arrived to the Grammys on Sunday wearing .... drum roll ... a suit and tie. Well, a bow tie actually.

And you thought the sexyback jokes were endless.

CBS has put the screws to the fashion risk takers who want to show some skin at tonight's Grammys. Now that the memo is out, musicians now must decide whether to dial back. So we gotta ask ...
