It was Take Your Man to Work Day on American Idol Wednesday -- for Jennifer Lopez, at least, whose boyfriend Casper Smart visited her in the audience while the Fox smash taped.
The 24-year-old backup dancer, warmly greeted Lopez's fellow judges Randy Jackson and Steven Tyler -- and was the brunt of a good-natured joke from host Ryan Seacrest, who pointed out Smart chatting with two pals in the audience during a commercial break.
"Which of these three guys is Jennifer's boyfriend?" Seacrest said "Or is it the one who's shorter than Ryan Seacrest?" Lopez, 43, doubled over laughing as Smart looked a bit embarrassed as the audience cheered.
During most of the commercial breaks, however, Smart was by Lopez's side -- and she gazed on him adoringly and smiled as they chit-chatted.
Earlier in the day on Wednesday, Lopez and Smart, dating for just five months, were the subject of marriage talk -- all thanks to a bogus tweet by designer Roberto Cavalli. The tweet claimed Cavalli was designing a wedding dress for thrice-divorced Lopez, who split from Marc Anthony last July. A rep for Cavalli later explained the Twitter account had been hacked.
