On Tuesday's episode of Watch What Happens Live, the Real Housewives of Beverly Hills star confirmed she's once again going by Yolanda Hadid, reverting to the last name she had while married to Mohamed Hadid from 1994-2000 – and the same moniker as her three model children Gigi, 20, Bella, 19, and Anwar, 16.

"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," she told Andy Cohen of her maiden name. "And they said, 'No, you're our mommy, and we have the same last name.' "
Hadid, 52, also discussed her Lyme disease battle and called costar Lisa Rinna's involvement in a rumor that she suffers from Munchausen, a psychiatric disorder in which the patient pretends to be ill, "hurtful."

As for her December split from songwriter and record producer David Foster following four years of marriage, Hadid says she isn't embracing the single life.
"I haven't tried it yet," she said. "I'm still at home trying to get well."
