Although Kim Richards accused Lisa Vanderpump of lying to get out of attending her daughter’s graduation party, Breaking Celebrity News has learned the British restaurateur was honest about her prior commitments!

As Breaking Celebrity News previously reported, costar Richards claimed Vanderpump was spotted dining at SUR on the same day she'd claimed to be in St. Louis, Missouri, attending the 28th Annual National Alopecia Areata Foundation Conference.

“The truth is that Lisa was in St. Louis attending an event that is very close to her and Ken,” a source exclusively told Breaking Celebrity News.

During the 24-hour whirlwind trip, The Real Housewives of Beverly Hills star along with her adorable Pomeranian pup Giggy, who has alopecia areata, taped a Public Service Announcement for NAAF, met with conference attendees for an impromptu photo session before walking in Saturday morning’s Tortoise & Hair march.
