Brandi Glanville hooked up with Gerard Butler for a week this summer

The Real Housewives of Beverly Hills star Brandi Glanville was on Watch What Happens Live! tonight and while playing “Plead the Fifth” she dropped a celebrity hook up bombshell! After already pleading the fifth when asked what she would say to LeAnn Rimes if locked in a room with her for ten minutes, Brandi had to answer the next two questions.

Next up was “When is the last time you watched porn?” Brandi answered that she doesn’t really watch porn, but eventually answered “Last year.”

Then the fireworks began…

Andy Cohen: Who is the most famous person besides Eddie Cibrian that you have hooked up with?

Brandi Glanville: Uh, Gerard Butler.

Andy: Ooooooooohhh!! So was that like a one nighter?

Brandi: No, it wasn’t a one nighter, it was just like a little week of fun.

Andy: Oh, a week of fun! It sounds very fun! On the scale of one to ten, how fun was it?

Brandi: 11

Andy: So was that in the last year?

Brandi: Yeah. Over the summer.

Andy: While we were shooting The Real Housewives of Beverly Hills?

Brandi: Yes.

Andy: Wait, wait! Did you have the crutch?

Brandi: No, no. … I’m so going to hell for this.

Andy: No you’re not – it’s Plead the Fifth! You had to answer!

So there you have it! Brandi Glanville hooked up with Gerard Butler this summer for about a week! Wow! That’s why they call it Watch What Happens Live! folks!

UPDATE – Check out this quote from Gerard Butler about rumors he was seeing co-star Jennifer Aniston back in May of 2011:

“We have a natural chemistry – you can see it in our magazine shoot and the film. We have a great time together. But here’s the thing – while they’re accusing me of being with Jennifer, I’ve probably been off somewhere else doing damage with someone else. My last two girlfriends, one was 2 years, the other 18 months, nobody ever found out I was dating them. I’m pretty good at keeping that silent. I get laid less now than I used to because I’m more paranoid now. I’m nowhere near as naughty as I used to be.”

UPDATE – It turns out the Gerard Butler and Brandi Glanville hook up is old news, if news means a juicy bit of gossip in a tabloid! Back in August Life & Style reported that Brandi and Gerard “engaged in a public and steamy make-out session on the beach in Malibu on Aug. 27. From their article:

“They were at a private beach party — drinks were flowing, and one thing led to another,” an eyewitness tells Life & Style. “Next thing you know, they’re dancing together to some music, hands started getting frisky and it was a full-on make-out! Everyone saw it. One girl tried to snap a photo of it on her phone, but Gerard politely asked for privacy.”

But that’s not all! Gossip on the ol’ interwebs suggests Brandi had some negative things to say about Gerard’s tackle! A claim that seems to be backed up by a very angry woman named Ginger Hines who tweeted the following after Brandi’s shocking announcement on Watch What Happens Live!

@brandiglanville Let’s clear things up about Gerard Butler…1.) You got drunk & threw up off of his balcony 2.) He slept w/ u & never called u again 3.) You told friends he has a skinny, curved penis ….So to make it very clear..it was a one night stand, not a week, he regrets it according to a certain Malibu Beach Bunny, and you’ve never heard from him again. Just making sure everyone knows the REAL story about your celeb hook-up.

And this Us weekly “Hot Stuff” video from September 9 claims that the Malibu hook up wasn’t the first time for Brandi and Gerard, so maybe Brandi is referring to a completely different week altogether! (That would seem to make her “summer” comment make more sense.) The Brandi/Gerard portion is the last, starting at right around the 2:25 mark:
