Pop singer Jennifer Lopez and hubby Marc Anthony have quashed the rumors of an impending breakup by performing a romantic duet at a party celebrating the inauguration of President Barack Obama. Anthony was performing at the Western Ball in Washington, D.C. on Tuesday night after Barack Obama was officially welcomed into the White House. Anthony praised his wife throughout his performance and before launching into his decade old-hit, "You Sang to Me," he told the crowd, "I wrote this next song about Jennifer. I must have been psychic. She didn't get the point, but eventually it worked." And for his final song, Anthony welcomed wife Jennifer on stage, inviting her to sing an upbeat ballad with him in Spanish. The pair embraced and shared a kiss at the end of the set, with Anthony telling the audience, "Man, she's cute."
