And while we're at it ... we gotta ask ...

"I definitely feel naked," Kate said during the shoot ... "Because I am."

Vida Guerra Emergency Boob Surgery But the Rack Is Intact

Model Vida Guerra -- famous for her backside -- had emergency surgery on her other money-maker yesterday -- replacing a breast implant that was creating a serious health crisis ... TMZ has learned.

Vida posted a pic of her exposed chest Tuesday morning ... showing her right breast covered by a large gauze pad. The problem was scar tissue forming around a gel implant.

Vida tells us back in 2011 she replaced saline implants with fancy new gel ones -- 450cc (or a full C cup). When she recently started having back pain and trouble breathing ... docs told her scar tissue had formed and had to be removed, along with the implant itself.

Vida got a new left implant during her 24 hour hospital stay -- but she's home now, doing something she never gets to do ... PIG OUT!!!

The fitness fanatic confesses she's been eating "everything in sight" ... especially pizza. Docs have cleared her to start working out again in a month.

Boob job lesson of the day: Vida says, "If I could do it over again, I wouldn't have. It's just more problems in the end."

And the front.

Lindsay Lohan Shows Support for Mom But None for Her Boobs

Lindsay Lohan just arrived at her mom's house on Long Island -- this after Dina Lohan's arrest for an off-the-charts DWI -- and she was definitely lacking in the support department.

Lindsay showed up in a black Porsche with her sister, Ali and an unidentified guy -- flashing a ton of side-boob as she walked into the house.

Shortly after Linds showed up ... her old attorney Mark Heller walked out of Dina's pad, and announced he's representing her in the DWI.

Heller pointed out Dina is a first time DWI offender with no prior record (criminally, anyway) -- and as a result he felt she would be treated with "fairness." Translation: he's hoping for no jail time.

As we previously reported ... Dina was arrested Thursday night ... and cops say she had a BAC of 0.2 -- nearly 3 times the legal limit.

Dina's still laying low -- the only sign of her all day was in the doorway as she let a friend out. She looked ... hazy.

'Sports Illustrated' Model Topless Pic Surfaces ... with John Legend

Sports Illustrated supermodel Chrissy Teigen just posed for a topless photo shoot with her fiance John Legend ... and now one of the topless pics has surfaced on the web.

The photo appears to be a frame from John's music video for his song, "All Of Me."

As of 8:11 AM PT, the photo is still up on Instagram ... but if you wanna see it, you better act fast -- we're guessing it won't be up long.

A pink and white beach blanket just barely managed to conceal the goods ... as Ashley filmed a scene for "Staten Island Summer" at the Great Kills Swim Club ... where some of the locals were used as extras.

The movie's about a couple of dudes who take jobs as lifeguards while trying to figure out what to do with their lives.

Ali Lohan Models But Lindsay's BOOBS Steal The Show!

Lindsay Lohan is a big supporter of her lil' sis Ali's new modeling career ... but it was Lindsay -- and her boobs -- who stole the show yesterday at Ali's fashion show in NY.

19-year-old Ali was one of the featured runway models at the Wendy Nichol fall fashion show in SoHo ... a show that seemed to combine Lord of the Rings chic with a goth funeral.

Lindsay wasn't involved in the show -- but dressed the part anyway, sporting a low cut number that highlighted her Baggins (LOTR joke!).
