Jennifer Lopez & Marc Anthony: 'American Idol' Performance!

Jennifer Lopez and hubby Marc Anthony hit the stage during the season finale of American Idol on Wednesday (May 25) at Nokia Theatre L.A. Live in Los Angeles.

The 41-year-old Idol judge joined Marc as he sang Hector Lavoe‘s “Aguanile” – but instead of singing, J. Lo did a sultry dance number in a fringe leotard and heels!

“Now we know what they do at home!” host Ryan Seacrest said after the couple ended their performance with a kiss.

“Thank you all my #lover?s for all your support! Tonight was amazing!” Jennifer tweeted.

FYI: Marc is wearing David Yurman‘s black diamond Albion cufflinks and shirt studs.
