Selena Gomez recently revealed that Taylor Swift keeps her grounded and that she's "great to have around," leaving fans wondering if the "You Belong With Me" singer killed Justin Bieber's hopes of getting back together with his ex-girlfriend.

Taylor Swift, who was spotted sitting next to Selena Gomez at the VMAs, is noted for criticizing Justin Bieber's behavior and his relationships with women.

But Taylor Swift might not be the only person in Justin Bieber's way.

Selena Gomez revealed to E! News that she has a crush on actor George Clooney, leaving fans buzzing about his role in her on-off love affair with Justin Bieber.

Although Selena Gomez has mentioned that she is single and that she prefers it that way, the "Come and Get It" singer has made headlines for her public signs of affection for Justin Bieber.

George Clooney isn't the only person Justin Bieber might need to keep an eye on.

Romeo, one of Justin Bieber's closest friends, wants to date his friend's ex-girlfriend, Selena Gomez.

When asked what he wanted for his birthday on Monday, the rapper had just one wish. He said:

"How about a hot date with Selena Gomez?" PerezHilton.com reports. "Selena, she's like the girl version of me, man. She's amazing."

Selena Gomez's parents sat her down after her 21st birthday party and staged a Justin Bieber-intervention, telling her that if he didn't get out of her life, they would, HollywoodLife reports.

"They told her this was the last straw," a source reportedly told Life & Style. "They told her Justin was a really bad person. They said she has to rid him from her life, otherwise they can't be a part of her life - her new baby sister included."
