Sexy stars JENNIFER LOPEZ and EVA LONGORIA PARKER added a touch of Hollywood glamour to the White House on Tuesday night (13Oct09) when they joined U.S. president BARACK OBAMA at a bash to celebrate Hispanic music. The lovely Latinas were among the 400 guests who gathered in Washington, D.C. to enjoy sets by Gloria Estefan and band Aventura at the high-profile In Performance at the White House: Fiesta Latina event, which was hosted by Longoria Parker, comedian George Lopez and actor Jimmy Smits. Obama even accepted an invitation to dance with singer Thalia, after she approached the leader and asked, "Mr. President, with all due respect, will you dance with me?" The concert was part of a music series launched by First Lady Michelle Obama to celebrate the different genres and cultures. Earlier in the day, Desperate Housewives star Longoria Parker headed to Capitol Hill to voice her support for the proposed National Museum of the American Latino.
