American Idol: Jennifer Lopez, Marc Anthony & Sheila E. Put the Salsa in Season 10 Finale

¡WEPA! The salsa beats were in full swing as Marc Anthony took the stage and performing his rendition of Héctor Lavoe’s “Aguanile” on the finale of American Idol held at the Nokia Theater in Los Angeles, Calif. Wednesday night.

Adding sazón to the mix was his wife and Idol judge, Jennifer López, who emerged dancing a sensual routine for her hubby, wearing a barely-there white leotard and heels as veteran percussionist Shelila E. played the Timbales in the background.

López shaked shaked what her momma gave her, gyrating to-and-fro, making the crowd go into frenzy. The steamy performance ended in a lip-lock between her and Anthony.

"Now we know what they do at home!" American Idol host Ryan Seacrest said.

Other signature performances included those of Mother Monster Lady Gaga, Beyoncé who also performed with Idol’s ‘Top’ 12 Girls, and duets by Jack Black and Casey Abrams, Carrie Underwood and Lauren Alaina, and newly crowned Season 10 American Idol, Scotty McCreery and Tim Macgraw.

López’s fellow judge, rockstar Steven Tyler wowed the crowd, playing the piano and singing Aerosmith’s classic “Dream On.”

Spider man also webbed his way into the finale, as Bono and The Edge performed “Rise Against the Machine.”

Recreating the beloved scene in the first Spiderman movie, Spidey slowly descended upside down in front of López.

She teased him and slowly took off his mask enough to show his mouth and just when we thought she would lean in to kiss him, she playfully touched his lips and said “boop!”
