Adrienne Maloof certainly appears to be taking her divorce from ex-husband Paul Nassif in stride.

The 51-year-old business mogul is already dating a much younger man, Rod Stewart’s 32-year old son, Sean Stewart, and she’s been raving about the budding relationship to fans, but that’s not all. According to the TV and celebrity gossip site WetPaint, Maloof also previously dated Los Angeles mayor Antonio Villaraigosa before getting involved with Stewart.

“Adrienne and Antonio went on several discreet dates beginning late November,” said a source who spoke to Radar Online. "This was, of course, before things with Adrienne and Sean got hot and heavy and they became serious."

“Adrienne’s friends were hoping that she would settle down with the Mayor, despite his well-earned playboy reputation. After all, Antonio has a job … Sean doesn’t!" the source added. “But she chose Sean, and that’s left a lot of people scratching their heads."

Maloof has already defended the relationship to the media, telling People magazine that Stewart is “"a lot more mature than a lot of 60-year-olds at this time in his life.”

"I'm a modern business woman. I don't think of age ... He understands my world, the entertainment industry and being a public figure,” she added.

Stewart’s biggest claim to game so far has been appearing on the second season of “Celebrity Rehab with Dr. Drew,” where shared his difficulties overcoming substance abuse. But according to Maloof, Stewart’s partying ways are long behind him.

"That was when he was a young kid," Maloof told People. "He's been clean and sober for years."

"It's about how good of a person you are,” Maloof added in another interview with TMZ. “[Sean] is a very funny guy. He's very giving, he mentors at the mission, works with at-risk children, and gives his time and money to get children off the streets."

"Age is just a number,” she said.

And despite the previous bad blood between Maloof and Nassif, her ex-husband seems to be supportive of her love life, telling TMZ, “as long as she’s happy, that’s all I care about.”

The two battled in September, when Maloof filed for a restraining order against Nassif, alleging that he had been physically violent with their sons, among other claims. Nassif called the claims “utterly false” and added that the divorce proceedings had become “a bit of a circus.”

"I'm going to stay utterly focused on [my children's] well-being and the knowledge they need equal time with both of their parents both of whom love them very much. I'm sure all will be fine, and when all the emotion of the moment dies down, Adrienne and I will be terrific co-parents,” Nassif told TMZ.
