Tom Cruise and Katie Holmes partied late into the night in Miami on Saturday.
The couple were among the star-studded crowd at the Ocean Drive magazine and MarketAmerica.com pre-Super Bowl party in South Beach, where Fergie and her Black Eyed Peas bandmate Will.i.Am kicked off the night's concert.
Cruise pal Marc Anthony headlined the event, crooning several of his hit songs – plus a cover of "Hotel California." Anthony was also joined onstage by his wife Jennifer Lopez, who sang with her hubby.
Cruise and Holmes – along with Cruise's sister and his son Connor – rocked out in their seats on the side of the stage as Anthony and Lopez performed.
"She's quite a dancer," one partygoer said of Holmes. "They were really into the music."
Other celebs at the concert included Scarlett Johansson, Matt Leinart, Tara Reid, Marlee Matlin, Leah Remini, Jeff Gordon, Joey Fatone and Stacy Keibler.
When the show ended just after midnight, a huge fireworks display lit up the sky over the Atlantic Ocean.
Afterwards, the party shifted to South Beach's hip lounge Mokai for the private CAA sports party. Cruise and Holmes danced to a mix of rock and hip-hop, including songs like "Sweet Home Alabama" – behind a wall of security guards.
Still, partygoers snapped photos of the affectionate couple, who kissed and cuddled as they danced. The pair, along with Connor, stayed at the club until nearly 2:00 a.m.
Also drawing attention at the party were Nick Lachey and Vanessa Minnillo, who chatted with friends throughout the night.
