Turns out she's more cougar than fox.

Vivica A. Fox had some big news over the holiday weekend, when her boyfriend Omar "Slim" White popped the question, her rep confirms to E! News.

The 27-year-old Atlanta club promoter—who is nearly two decades her junior—proposed the day after Christmas with a sweet diamond ring.

And how big was the sparkler? Read on...

Just 8 carats, that's all.

The Curb Your Enthusiasm star stepped out flashing a brand-new bling while on vacation with her man in Miami.

"She is indeed engaged," Fox's rep tells E! News. "Both her and Omar are very happy."

At LeBron James' 26th birthday party at Coco de Ville as well as at STK at The Gansevoort Hotel, the couple was snapped looking happy alongside Kelly Rowland, Drake and Tyrese Gibson.

"She arrived in a black SUV with Slim and was showing off her ring to everyone," said one guest.

The two have been seeing each other for more than a year.

No date has been set yet, but it will be the second marriage for Fox, who was wed to singer Christopher Harvest in 1998. They divorced four years later.
