"Real Housewives of Beverly Hills" star Adrienne Maloof is the latest celebrity to take a dip in the cougar pool.
The 51-year-old is dating Rod Stewart's troubled son Sean Stewart, who is 19 years her junior.
Stewart, 32, and Maloof were seen out and about in Beverly Hills on Jan. 19 after enjoying a romantic dinner at the restaurant Crustacean. The pair was spotted kissing and cuddling as they left the California eatery -- and there are pictures to prove it.
Maloof reached a divorce settlement with her husband of 10 years, Paul Nassif, in November, after claiming he had physically abused her throughout their marriage. And Stewart, a recovering addict who has made headlines over the years for his run-ins with the law, was previously engaged to Kansas City Royals star Jason Kendall's ex-wife Chantel Kendall, who was nine years older than him.
But Maloof and Stewart aren't the only stars who share a May-December romance.
