Los Angeles: Songstress Selena Gomez is said to be relieved with rumours that her former beau Justin Bieber is now dating reality TV star Kourtney Kardashian.

Gomez, 23, who is reportedly dating One Direction band member Niall Horan, is glad that there's buzz that Bieber is in a relationship, as she no longer has to feel guilty about the fact that her love-life has moved on, reports hollywoodreporter.com.

"Selena was under the impression that there was no one serious in Justin's life. At least that's what he told her. So when Selena and Niall took their friendship to the next level, she actually felt concerned with how Justin would take the news,” said a source.

"Now that she knows about Kourtney, she doesn't feel bad for Justin one bit. She's more relieved than ever that she's moved on with such a great guy,” the source added.
