The news was first revealed by none other than the fashion designer's ex-husband, Russell Simmons, who spilled the beans on Twitter. "All of us love @OfficialKimora but the fact is she is happily married," he wrote on Wednesday, Feb. 19. "Tim has been family for a while now."
The tweet was in response to rumors that Simmons, 38, was dating rapper Birdman, who posted a photo of himself with the former model via Instagram. The caption read: "S/O @OfficialKimora luv of my life. Thank u 4 everythang u did and do 4 me RICHGIRL RICHGANG."
Simmons and Leissner were first linked last year, following her split from longtime love Djimon Hounsou, with whom she has one son, Kenzo, 4. (She also has two daughters, Ming, 14, and Aoki, 11, with her ex-husband.)
On Christmas Day 2013, Simmons and Leissner were spotted walking on the beach together in St. Barts, where they were vacationing with her three children. She has yet to confirm her marriage.
