Kimora Lee
Simmons is officially off the market ... again.

The fashion designer recently tied the knot with banker Tim Leissner. Kimora's ex-husband Russell Simons broke the news via Twitter on Wednesday. 

"@OfficialKimora but the fact is she is happily married," Russell posted on his social media account.  "Tim has been family for awhile now." 

The hip-hop heavyweight posted the big news in response to rumors that his ex-wife was dating rapper Birdman

Simmons was spotted wearing matching rings with Leissner back in January at a Golden Globes after party ... so it looks like the two have been happily married for at least a month now.

The couple were first linked together last year, shortly after the mother-of-three split from longtime boyfriend Djimon Hounsou. Simmons has son Kenzo, 4, with Hounsou and daughters Ming 14, and Aoki, 11, with Russell. 

It's great to see that Simmons is so accepting of Kimora's new hubby -- talk about a modern family!
