It has been made clear during the recent Real Housewives of Beverly Hills Season 4 Reunion that Lisa Vanderpump and Yolanda Foster are no longer on good terms. But does Lisa believe there's any truth to rumors emerging this week that Yolanda and husband David's marriage is on the rocks?

Lisa is very close friends with Yolanda's ex-husband, Mohamed Hadid. And while Lisa was initially friendly with Yolanda, their friendship has gone south. Indeed, Yolanda and Lisa's huband Ken Todd exchanged harsh words during the Season 4 finale, with Ken pointing out that David doesn't frequently attend events with Yolanda. 

This week, reports surfaced that Yolanda has started using her previous last name, Hadid, leading some media outlets to wonder if the two are headed for divorce. The couple is also in the process of selling their Malibu home.

So one of Lisa's Twitter followers asked her if she thinks Yolanda and David might actually be splitting up. "Nooo, I never listen to gossip..." Lisa responds. "I am sure not." 

Phew! We love that Lisa is supporting Yolanda and David, even though she isn't particularly close to Yolanda at the moment. Indeed, Yolanda and David's rep tells the Daily Mail that they are "happily married." The rep claims that the rumor only started because Yolanda was mistakenly referred to as "Yolanda Hadid" in the credits for Lady Gaga's "G.U.Y." video, which Yolanda appeared in.

Do you think Yolanda and David are having issues? And are you surprised by Lisa's response?
