Not Exactly BFFs! Lisa Vanderpump Calls Her Relationship With Kyle Richards 'Arduous'

Lisa Vanderpump is opening up about her relationship with fellow The Real Housewives of Beverly Hills star Kyle Richards, and it's obvious they're not the best of friends.

Lisa dished about life behind the scenes of the RHOBH Tuesday, while co-hosting Anderson Live with Anderson Cooper.

When asked how she gets along with Kyle, Lisa said, "We've had many obstacles and hurdles. I think we are both very open and she can't understand why the relationships change but that's what happens."

As RadarOnline exclusively reported, Lisa has been making the rounds on national TV to promote her new book and spin-off reality TV show, Vanderpump Rules.

Lisa wasn't the only familiar face joining Anderson.

Hollywood veteran Betty White also stopped by and explained why there was never a "Golden Girls" movie, revealing the late Bea Arthur said no to the project.
