Kimora Lee Simmons hit the beaches of St. Bart's again on Wednesday, showing off her sexy curves while taking a dip in the blue Caribbean waters.

The newly single fashion guru -- she recently split from second husband Djimon Hounsou -- vacationed with her children and ex-husband Russell Simmons and his new girlfriend Hana Nitsche.

Nitsche was a finalist on the German version of America's Next Top Model.

Kimora and Russell were married on the island in 1998.
