NICK AND JESSICA REUNITED!
Since work has kept Jessica Simpson and Nick Lachey apart lately—she's been on the Dukes of Hazzard set in Baton Rouge; he's been in L.A. shooting an episode of ABC's Hope & Faith—the AMAs gave the couple a chance for a mini-reunion. Walking down the red carpet, Lachey told us their new trick for bridging the distance. "I send her dirty text messages," he said. Laughed Simpson: "I think it's cute." Postshow the pair joined Simpson's sister Ashlee for some partygoing before ending up at Guy's to listen to jazz until 2 a.m.

COUPLED-UP AT CLIVE'S
Record mogul Clive Davis held a post-AMA party at the Esquire House in Beverly Hills, but it looked more like the Love Shack, with Janet Jackson wrapped in Jermaine Dupri's arms, Josh Groban cuddling poolside with Love Actually's January Jones, and singer John Mayer guiding British actress Rhona Mitra (Boston Legal) through the party with his hand on her back. Although 'N Syncer JC Chasez shared a lingering, hands-on-her-bottom hug with Desperate Housewives' Eva Longoria, he's still coy about their relationship, saying only, "Life is good." Meanwhile a solo Jamie Foxx flirted with several women, entering one brunet's digits directly into his cell phone.

GWEN IN WONDERLAND
Forget the rabbit hole. Guests at Gwen Stefani's Alice in Wonderland-themed CD release party after the AMAs stepped into a private elevator and zipped up 13 stories for a rooftop soiree at L.A.'s downtown Standard hotel. Award-winners Alicia Keys and Sheryl Crow joined Pamela Anderson, Christina Applegate and husband Jonathan Schaech, Anthony Kiedis and reality king Mark Burnett to nosh on bite-size cupcakes, cookies and pumpkin pies while the video for her first solo single, "What You Waiting For?," was projected on the wall of a neighboring building. "It's been a really long, fun day," said Stefani, who opened the telecast by performing the single. "I hope it never ends." She and husband Gavin Rossdale then hit the floor and danced for an hour to Beyoncé, R. Kelly and Stefani's own remixes.

PARTY HOPPING

At midnight Lenny Kravitz unwinds from the AMAs with an acoustic jam session with Prince, playing along to DVDs of Ray Charles and Prince's 2004 tour before an invite-only crowd of 40, including Elijah Wood and Less Than Perfect's Zachary Levi.

TEEN PEOPLE PARTY, KEY CLUB, L.A. Party-hopper of the night Ashlee Simpson tells us she cut off her long hair for a role in the comedy Wannabe. Later her pal Bijou Phillips causes a fuss when a bouncer won't let the actress return to her table without a VIP wristband. Phillips tries to crawl under his legs and screams, "You don't know who I am!" So the bouncer picks her up and carries her out of the club on his shoulder.
