Justin Bieber 'stripper girlfriend' Diamond UPDATE: Selena Gomez's ex 'impressed' with real butt, drops $7000 on sexy dancer, 'makes it rain' during unreleased song lap dance

Earlier this month, "Heartbreaker" crooner Justin Bieber had an awesome time at Houstin's VLive strip club with a sexy dancer named Diamond. As Mstars previously reported:

Diamond, a popular (and curvaceous) stripper at VLive, tweeted about her steamy lap dance encounter with the 19-year-old pop sensation:

@1real_diamond: "@justinbieber Went The Fuk In Tonight!!"

@1real_diamond: "He Touched My A$ I Almost Fainted."

@1real_diamond: "He Was Like Its Real!!"

@1real_diamond: "I've Danced For A lot Of Celebrities And They Normally Don't Phase Me But Justin just Had Me In Shock!"

@1real_diamond: "I am now a @justinbieber Fan!"

Diamond's revealing tweets eventually went viral, and the Houston dancer was soon being talked about all over the web. But here's the thing, Beliebers - she's NOT dating the Biebs! The two were just having some fun, and Diamond was simply doing her job. In her first-ever interview with VH1's "Gossip Table," Diamond says:

- Bieber came to the nightclub with his entourage. Diamond and the teen sensation started chatting and listening to music in his VIP section.

- The "Believe" crooner was NOT drinking... it's an 18+ club. They don't even serve alcohol.

- Diamond actually danced to one of Biebs' new UNRELEASED songs! How exciting... she says the tune was "great."

- And YES, Diamonds did give Bieber a lap dance. She says he's a good, laidback guy... and he has soft hands.

- Biebs didn't talk about his ex-girlfriend Selena Gomez during the private dance... duh.

- Beliebers shouldn't hate - Diamond didn't do anything wrong, and neither did Bieber. He's a "teenager becoming a man," he's just doing his thing!

Now, in a recent interview with InTouch, Diamond released even more dirty details...

The Biebs dropped about $10,000 in a matter of 90 minutes. “I walked away with $7,000,” Diamond explains. "A few other girls split the rest.”

And Bieber LOVED the fact that Diamond was au naturel - "He grabbed my butt and asked if it was real, and smiled when I said yes."  

Diamond explains that the Biebs was pumped when the club played one of his new (and unreleased) songs - "That was when he made it rain... He went crazy!"

Sounds like one crazy night... but all in good fun!
