Russell took to Twitter to dismiss claims his ex was dating rapper Birdman, but his good intentions sparked a frenzy when he revealed Kimora was married.
"All of us love @OfficialKimora but the fact is she is happily married," he tweeted Wednesday. "Tim has been family for a while now. #gossipcop…"
While Kimora and Leissner were public about their relationship, their apparent marriage was never disclosed.
Kimora and Russell have two children together; Ming, 13, and Aoki, 10. The bride also has a son, Kenzo, 4, with ex Djimon Hounsou.
