Justin Bieber and Selena Gomez appear to be happier than ever now that they're seemingly back on, packing on the PDA during their romantic week in Texas. But one person who is allegedly unhappy with the reunion? Gomez's bestie, Taylor Swift.

Sources claim to Us Weekly that T. Swift is not happy that Jelena is back together and has distanced herself from the 'Come & Get It' singer because of it.

While we're not surprised that Jelena doesn't get Swift's seal of approval (remember when she was caught sticking out her tongue after Jelena kissed at the 2013 Billboard Music Awards?) we're not so sure we're buying the fact that the 'We Are Never Ever Getting Back Together' musician decided to end her close friendship with Gomez just over Bieber.

But, these sources claim, the rift between Swift and Gomez started before the Biebs came back into the picture -- apparently, Swift started edging away from her pal after Gomez allegedly had a brief fling with Ed Sheeran just to make Bieber jealous.

"After Selena pulled that move, Taylor started distancing herself," the source claimed to the magazine.

Hmmm. Again, not so sure we believe that either. While rumored to have hooked up, it was never confirmed that Gomez and Sheeran were ever anything more than friends.

Still, it looked like Swift definitely wanted to move Gomez away from the Biebs: she did reportedly set her celeb bestie up with One Direction's Niall Horan right before the inseparable duo started going public with their romance once again.
