Adrienne Maloof Casually Dating Rod Stewart's Son

Newly single Adrienne Maloof should move to Cougar Town. The 51-year-old recently struck up with Sean Stewart, Rod Stewart's 32-year-old son.

"This started as a business relationship and now we're casually dating," Maloof told People. "It's casual, real casual."

When Maloof says casual, she wasn't kidding! The couple were spotted Friday getting lunch at a McDonald's drive-thru.

Stewart's age doesn't seem to bother Maloof, who said her new beau's "a lot more mature than a lot of 60-year-olds at this time in his life," and is no longer the party boy he used to be. "He's been clean and sober for years," the Real Housewives of Beverly Hills star added.

Since striking up their romance, Maloof has faced some criticism concerning their age difference, but Stewart says those people are just sexist. "If men can date younger women, why can't an older woman date a younger man? It's sexist," Stewart told TMZ.

"It's about the person she is inside," he added. "Age is just a number. If there's a connection and someone cares about a person, that's what matters really."

Paul Nassif, Maloof's husband since 2002, filed for divorce in July.
