Rocker Rod Stewart's wildchild son Sean has embarked on an unlikely romance with U.S. reality Tv star Adrienne Maloof.

Sean Stewart went public with his new relationship on Friday (18Jan13), when he stepped out with The Real Housewives of Beverly Hills regular, who is 19 years his senior, and posed for photos as they headed to dinner in Los Angeles.

A source tells, "He's really good with her kids, and she thinks it's fun to be with a younger guy."

Newly-divorced Maloof, 51, has three young sons with her ex-husband Dr. Paul Nassif. The former couple finalised its bitter divorce in November (12).
