Janet Jackson & pals get into groove!

Record exec Antonio ‘’L.A.’’ Reid was staying at Acqualina: A Rosewood Resort in Sunny Isles Beach, where he and his entourage filled 10 suites. The group is here for three months to work on Janet Jackson’s new album along with Jermaine Dupri at Circle House Studios.

Jackson and a group of male and female friends — no sign of boyfriend Dupri — slipped in the back door of Privé on Saturday night for promoter Justin Levine’s Empire Events party. Holding court in Privé’s hip-hop section, Ms. Jackson, clad in white with form-fitting pants, shirt and shoes, showed off her svelte figure while sipping red wine and grooving to hits by Diddy, Jay-Z and a vintage Jackson 5 remix. At the next table: Scott Storch and Paris Hilton pal Brandon Davis — who seems to have found a new blond to replace buddy Paris while she’s in the slammer. According to a spy, Davis was cuddling with “a very busty blond who was hanging onto his arm.’’
