The holidays are a time to wind down and relax and no one needs that more than a certain mother of two, Shar Jackson tells OK!. Kevin Federline's ex and the mother of his first two kids offers his other babymama, Britney Spears, some sound advice as the year comes to a close.

"Take it easy. Enjoy the holidays. Lay low a little bit," she tells OK! at the Christopher Brian’s resort collection launch in West Hollywood.

The 31-year-old could use some R&R herself as the mother to four children, Donnie, 16, Cassie, 12, and Kori, 5, and Kaleb, 3, her children with K-Fed, whom she calls an "amazing dad."

"He's very loving and his kids are his number-one priority," she says.

While raising four kids as a single parent is hectic — thus rendering her love life nonexistent, she says — she wouldn't have it any other way. Motherhood comes first for the former Moesha star and career, second.

"In my extra time, I throw that career thing in, Shar says. "When you're a parent, everything is so funny so it's just nonstop laughter."
