Federline actually met Hernandez while he was still married to Spears. She interviewed him while he was promoting his rap album, Playing with Fire.

An insider told the Enquirer, "Kevin is definitely thrilled with Liz. He talks about her all the time — how smart she is, how she's marketed herself so well, and how beautiful she is. He's serious about her…He has tons of modeling pictures of Liz in his home."

Perhaps worried about her reputation, "Liz is trying to keep [the romance] quiet because she doesn't want it to get around work," says the source. "But Kevin can't help but brag about his conquest to his friends and family."

Liz proves that the way to a man's heart is through his stomach. Says the snitch, "She likes to cook, and Kevin loves that because he always did the cooking for both Shar and Britney."
