We’ve all heard, “What Happens in Vegas, Stays in Vegas,” but after Kim Kardashian’s bachelorette party, Lala Vazquez tells RumorFix, “I want that to stay in Vegas.”

We don’t know what that is. Carmelo Anthony’s wife could be talking about the little person stripper — Mighty Mike — or the Midori cocktails.

But, one one thing’s for sure, Kim’s BFF says the party at the TAO at the Venetian “definitely was fun.”

She, Brittny Gastineau and Kim’s sisters, Khloe and Kourtney, were flown in by private jet to the lavish party.

Lala, who is filming Act Like A Lady, Think Like A Man, is helping Kim plan for her Big Fat Armenian TV Wedding.

While La La is honoring Kim’s wishes by keeping details secret, she says, “I’m one of her friends, so I’m doing things that a friend does — and just being there for her. It’s gonna be a fun time.”
