This was later followed by another post, where Marcille and her diamond ring are backdropped by a Christmas tree. She said in the caption that she is "quite happy" as "Santa showed out this year."

Last month, the Los Angeles native also used Instagram to announce that she was five months pregnant with Sterling's child. The photo showed Marcille, her beau, and her three-year-old daughter Marley.

"We're Expecting!!!!! 5 months in and we couldn't be more excited!!! @miketsterling gets a mini me and #Marley gets a sidekick," the model shared in the post.

Marcille rose to fame in 2004 after winning the third cycle of "America's Next Top Model."

In 2008, she moved from modeling to acting when she played Tyra Hamilton in the CBS noontime series "The Young and the Restless" for 72 episodes until 2009.

Four years later, Marcille began dating L.A. rapper Kevin McCall, the father of her first daughter Marley. They broke up in 2015.

In September, Marcille revealed to Us Weekly that she is joining the 10^th season of "The Real Housewives of Atlanta," not as a regular cast but as a close friend of one of the series regulars. "I'm so excited to join NeNe [Leakes] and the ladies for the 10th season of RHOA. Atlanta and America, get ready," she said in an official statement.
