Miley Cyrus has sparked rumors she's back with ex-boyfriend Carter Jenkins after the two were spotted at a Kings of Leon concert in Los Angeles over the weekend.

Jenkins, who briefly dated the teen sensation in between boyfriends Nick Jonas and model/singer Justin Gaston, even blogged about his night out with his ex on Twitter.com. He wrote, "Awesome show & very fun night with @mileycyrus."

Cyrus and the actor, who is currently shooting romantic comedy Valentine's Day with the singer's pal Taylor Swift, joined Justin Timberlake and Jessica Biel in the technician's booth at the Forum concert.

The foursome attended the backstage VIP party after the show, according to Eonline.com.

Kings of Leon shows have become a hotbed for new celebrity romances - Leann Rimes and Eddie Cibrian went public with their link up at the Los Angeles show on Saturday night and Twilight stars Robert Pattinson and Kristen Stewart were reportedly spotted kissing at a Canadian show earlier this month.
