Kate Walsh is certainly sexy when she strips off those scrubs!

The 45-year-old plastic surgery-free actress wasn't shy about showing off her absolutely fabulous bikini body on the beaches of Miami this week, frolicking around the shoreline with her hunky boyfriend, and Breaking Celebrity News has the photos.

Walsh, who arrived in South Florida over the weekend, flaunted her fit figure in a simple black bikini as she went for a swim in the clear Atlantic Ocean.

"Paps just shot my sweet, skinny fat in south beach…ugh, I think they got inside my belly button #whiteladya**andbellysyndrome," Walsh hilariously tweeted.

During her vacation, the actress dined at Nobu, Zuma, Casa Tua and Michael's Genuine, and also visited Key West.

As Breaking Celebrity News previously reported, Walsh, who recently stripped down to her birthday suit for the March 2012 cover of Shape, declared that she wouldn't go under the knife but doesn't judge her peers who have.
