Lisa Vanderpump wasn't thrilled with Brandi Glanville's hookup with a 23-year-old man in Amsterdam.

A couple of weeks ago, Glanville was seen going out on a date, and hooking up with a man from Amsterdam named Andre. In a sneak peek of the upcoming Real Housewives of Beverly Hills reunion, Vanderpump, whose son, Max, is a close friend of the man, spoke her mind.

"To me, it's disgusting," Vanderpump told reunion host Andy Cohen in a Perez Hilton sneak peek on Friday. In response, Glanville told Vanderpump, "Well, guess what? I f**ked him, and it was great."

Vanderpump went on to claim Andre denied having had sex with Glanville during her time in Amsterdam. According to the restaurateur, Andre explained, "Oh no, Lisa, I didn't have sex with her because she was too drunk."

Glanville, however, insisted she did sleep with Andre -- twice.

"We had sex both nights," she told Vanderpump.

Kyle Richards was also turned off by Glanville's date with Andre, and spoke of her distaste for the matter in her Bravo blog.

"Brandi was on a 'date' with Max’s friend. It all seemed creepy and strange, but I suppose Brandi would say (even though we’re four years apart in age) that I’m just a 'Menopause Mama.' To each his own," Richards wrote.

To see this and more, tune into The Real Housewives of Bevelry Hills season five reunion on Tuesday at 9 p.m. on Bravo.
