Rachel Barnes may have some serious on-screen chemistry with 18-year-old superstar, but she reassured his Beliebers that not only is she in a relationship but she is actually married so shouldn't pose any kind of threat, and told TMZ:

"Justin and Selena are adorably inseparable and I, myself, am already married... I'm a Belieber, but he's not my boyfriend."

"It's been great to be a part of the Bieber madness ... even if only for a song."

It was revealed earlier today (May 6) that Bieber's music video for 'Boyfriend' broke an impressive record after it attracted over 8 million views in 24 hours on VEVO. It also received over 12 million hits in just 2 days on YouTube.
