There's a very shocking report about pop stars Justin Bieber and his girlfriend Selena Gomez. According to In Touch magazine, the two were allegedly spotted doing lines of cocaine at a nightclub in Los Angeles and the whole thing was caught on video.

The source said the couple has been doing a lot of partying at different L.A. hotspots like Bootsy Bellows and 1Oak. Reportedly a secret tape is now being shopped around that shows the "Come and Get It" singer and her "bad boy" boyfriend allegedly snorting cocaine at 1Oak on June 16.

"They have been partying nonstop, they clearly aren't worried about their behavior," a source told the tabloid, adding that "someone's trying to get paid" for the video.

"They got caught doing lines," the source added, but said "the video is pretty dark and fuzzy."

According to Radar Online, police showed up to Gomez's Hidden Hills home the following day on June 17 because her neighbors were complaining about loud noises. The cops told the 21-year-old singer to keep it down.

In Touch's source claims that Gomez's family is "terrified it won't end well" for her.

"This time, they think Selena is going to have to hit rock bottom before she realizes Justin isn't good for her," the source said. "She's pretty much lost most of her friends and family because of this toxic relationship - and she still doesn't care."

"This road she's taking... it's all just so scary," the source added.

According to Hollywood Life, Bieber and Gomez are getting very serious about their relationship and are even supposedly talking about getting engaged. A source told the site that the "Boyfriend" singer is finally ready to "settle down" and start a family.

"Justin is talking about proposing to Selena, he's looking for the perfect rock for his princess," the source told Hollywood Life. "He's been telling her she's the only girl for him, that he's ready to settle down and have babies."
