Adrienne Maloof and Sean Stewart
Splash News Online
Adrienne Maloof wants to make one thing clear about Sean Stewart: "We are not living together. He has his own place. He has a nice place."
Otherwise, she tells PEOPLE, what you've read is true: The 51-year-old, recently single
star of Real Housewives of Beverly Hills
is, in fact, enjoying a budding relationship
with the 32-year-old son of Rod Stewart.
"This started as a business relationship and now we're casually dating," she says, emphasizing, "It's casual, real casual."
Stewart, she says, is "a lot more mature than a lot of 60-year-olds at this time in his life," and he's long since left behind his partying ways.
"That was when he was a young kid," says Maloof. "He's been clean and sober for years."
Maloof, looking great and sounding carefree, with no sign of her recent nasty divorce
, notes that her family "has always been in youth-oriented businesses" – they run a Las Vegas casino among other enterprises – so she can relate.
"I'm a modern business woman," she says. "I don't think of age."
And the fact that Stewart comes from a famous family is a plus. "He understands my world, the entertainment industry and being a public figure," she says.
So what does she think about Sean's father, the legendary Rod, who is still going strong at 68?
"His dad is lovely," she says, "A very nice person."
