Rock your body, girl! Justin Timberlake had all the ladies swooning during Taylor Swift's 1989 World Tour show at the Staples Center in L.A. on Wednesday, Aug. 26, but one in particular got to go home with him — Jessica Biel. An insider tells Us Weekly that the singer's wife was in attendance to cheer on her man in his first stadium performance since welcoming the couple's son, Silas, back in April.

Biel, 33, wasn't alone though. Her mom, Kimberly, was alongside her as Timberlake, 34, belted out his 2013 song “Mirrors." (Stars such as Reese Witherspoon, Nina Dobrev, Julianne Hough, Topher Grace, Alessandra Ambrosio, Jack Antonoff, Jaime King, and Mae Whitman also snagged tickets for the big night.)

"Jessica was clapping a ton and singing along to Justin's performance. She was clearly loving it!" the source says. "She left shortly after Justin's performance."

Swift was just as ecstatic to welcome the former boy bander to the stage. "I'm obsessed with his music, you're obsessed with his music. I think it's the only thing in the world everyone has in common," the "Style" singer, 25, told the crowd. "He has been a great friend to me. I can't believe I'm about to say this — Justin Timberlake is here!"

As exclusively reported, Timberlake recently surprised another audience with his vocal chops. The new dad sang “Señorita" while attending the June wedding of Biel's close friends Dana Panzer and Amy Wicker in Norwalk, Conn.
