So happy together! A newly dark brunette Stacy Keibler and boyfriend Jared Pobre looked happy cozying up to each other at the Ciroc Presents Bootsy Bellows Super Bowl 2014 pre-festivities on Jan. 30 at the Liquid Cellar in New York. "They are very serious," a source tells Us Weekly of the couple.

The typically-blonde Supermarket Superstar host, 34, has been gradually darkening her long locks since splitting from boyfriend of two years, Oscar winner George Clooney, last July. She went brunette last fall for New York Fashion Week, around the time she started stepping out with 38-year-old tech entrepreneur Pobre. (Us Weekly confirmed the two were dating after they were first spotted together in Paris in September.)

The latest shade seen on the former pro wrestler -- a chocolate color infused with caramel-hued lowlights -- is Keibler's darkest yet. The source adds, "She isn't used to her new hair color but loves it." The former TV show host paired her new hair hue with a bold red lip color, light smokey eye and long-sleeve black top. Her beau looked handsome in a plaid button-down shirt as he protectively wrapped his arm around Keibler at the party.

"They have been friends for four years," the source continues of the cute couple's roots. And it looks like Keibler's high-profile split from one of Hollywood's most-eligible bachelors last year actually helped her realize that true love was still a possibility: "She told me Jared is 'the one,'" adds the insider.
