Holy rock! Kimora Lee Simmons has stepped out for the first time since secretly tying the knot with boyfriend Tim Leissner. The fashion designer was photographed arriving at LAX airport in L.A. on Friday, Feb. 21 wearing a gorgeous sapphire ring on that finger.

Simmons, 38, dressed casual in tight-fitted jeans, a white t-shirt, and a light brown cardigan while donning the huge sparkler. Last month, she sported the same piece on her right hand while attending Netflix's 2014 Golden Globes after party in Beverly Hills with Leissner.

Us confirmed on Feb. 20 that Simmons wed banker Leissner after her ex-husband Russell Simmons first revealed the news via Twitter.

"All of us love @OfficialKimora but the fact is she is happily married," the 56-year-old business mogul tweeted on Feb. 19. "Tim has been family for a while now." (The Def Jam co-founder's tweet was in response to rumors that his ex was dating rapper Birdman.)

Simmons and her new hubby first went public with their relationship last year. The designer split from longtime love Djimon Hounsou in 2012 after five years together; they share son Kenzo, 4. She also has daughters Ming, 14, and Aoki, 11, with ex Simmons. The pair divorced in 2009 after 11 years of marriage.
