Yolanda Foster is going back to what she knows -- and that's her former married name "Yolanda Hadid."

The Real Housewives of Beverly Hills star has filed for divorce from David Foster and has dropped the music man's name but instead of going to her maiden name of van den Herik, the Dutch lady has opted to go back to the name she took when she was married to Mohamed Hadid from 1994-2000, who is the father to her three children Gigi, Bella and Anwar.

While on Watch What Happens Live!, the personality, who has been struggling with Lyme disease for the past few years, explained that she wanted to have the last name as her children.

The blonde told Andy, "I talked about it with my kids. I never dropped the name Hadid because I have three children with that last name, and I asked should I go back to van den Herik. And they said, 'No, you're our mommy, and we have the same last name.' "

Uhh we guess we get that logic, but we still think it's weird that she switched one ex's last name for another's. Just go back to your maiden name!

While on the show, the 52-year-old talked about having Lyme and how it was "hurtful" when Lisa Rinna says that she suffers from Munchausen, a psychiatric disorder in which the patient pretends to be ill.
