It's time for Lisa Vanderpump to show the whippersnappers how to get sexy on next week's episode of Vanderpump Rules.

In this preview video clip, Lisa plans a surprise 45th birthday party for her SUR business party Guillermo that he will definitely never forget.

"Stassi and Katie used to take burlesque lessons, so we thought it'd just be fun for them to get their pink feathers out of the attic and treat Guillermo," Lisa explains.

However, Guillermo isn't a huge fan of surprises. "He's going to have a bloody heart attack," Lisa predicts. "So the more he hates it, the more we love it."

Then, we see Lisa try on the pink feathers and boas for size. "They think they've got the market cornered on sexy," Lisa says. "Hey, girls  I invented sexy. There's still life in the old dog yet."

One of the girls then strips down to nothing but pasties covering her nipples, but Stassi isn't feeling that. "Fk no," she declares. "If I were to wear pasties, they'd probably be... right there [pointing around her stomach]."

Lisa isn't thrilled that business partner Nathalie says no to the pasties. "Well, Nathalie wants them all covered up," Lisa grouses. "She might as well get a couple of nuns down here. What's her problem? She's bloody French  they haven't seen a bra in years." You tell her, Lisa!
