She may be a Real Housewife, but that doesn’t make Kelly Bensimon cool, according to her kids.

“They think I’m their mom,” she said of her daughters, Sea Louis, 12, and Thaddeus Ann, 10. “Because I’m their mom I’m not really cool, but their friends like me, so I guess my cool factor is like a two on a [scale of] one to ten – better than a zero.”

Like most children fear that their parents will embarrass them, the Real Housewives of New York City star said her daughters are no different, and have told her to “tone it down” in the past.

“They tell me to wait outside the school and not come in and not to embarrass them,” Bensimon, 42, told PEOPLE at Tao Las Vegas’s 5-year anniversary party Saturday. “I’m like, I’m not even saying anything.”

Retired from modeling and now a reality star, author and jewelry designer, Bensimon said she and her children have a great time together and she hopes that they can learn from her as not only a mother but as a career woman, too.

“For them it’s something very aspirational,” she said. “You know, there are different chapters in your life and that’s what I want them to know.”
