Sara Ramirez Flashes Her "Anatomy"

8/6/2007 3:54 PM PDT
"Grey's Anatomy" starlet Sara Ramirez got her groove on to J.Lo's "Get Right" -- by dancing on a table and hiking up her dress at TAO in Las Vegas on Saturday. McSteamy!

The 31-year-old Tony winner jumped onto the catwalk at the Venetian hotel club, while celebrating at former co-star Kate Walsh's bachelorette party. Girls gone wild!

Sources tell us Ramirez, Walsh and 15 girlfriends partied into the AM, after gorging on platters of sushi, Kobe beef and chicken pad thai. Is there a doctor in the house?!
