Spears, 33, who started dating Ebersol about six months ago, said the boys adore him, reported People magazine.
"They relate to him really well and they have fun together. He's refreshing to be around and really light-hearted," she said.
While her long-running Planet Hollywood residency is a big hit, the superstar's true passion is being a mother to Sean Preston, nine, and eight-year-olf Jayden James.
"My kids come first in my life, bottom line," said Spears, who shares parenting duties with her ex-husband Kevin Federline.
