The Real Housewives of Beverly Hills star and former 'N Sync singer met up Thursday with their significant others Ken Todd and Michael Turchin for dinner at a LGBT fundraising event in L.A.
"Double date night at Lambda Legal's Liberty Awards (evil demon back left)," Bass posted on Instagram with a pic of the smiley foursome at their table.
He posted another photo of him and Vanderpump with the caption, "At Lambda Legal event in LA w the fabulous @lisavanderpump - She is gaying it up this week! Just saw her in the pride parade!"
The reality star looked gorgeous in a white dress and diamond earrings while Bass looked dapper in a gray suit and blue tie.
Nothing like a night out with Lisa and Lance!
