Selena Gomez could be a single lady again soon — even though she just started dating The Weeknd!

Although the pair was spotted together after the 2017 Grammys, In Touch can exclusively reveal that the former Disney star, 24, is "sabotaging" her new relationship with the rapper — whose real name is Abel Tesfaye, 26, just before he kicks off his Starboy: Legend of the Fall 2017 world tour.

“Selena’s paranoid that fans will be throwing themselves at The Weeknd and he’ll be tempted to stray,” says a source, who adds Selena has been begging to join her boyfriend on the road. “She’s so scared that she’s threatened to dump him if he doesn’t let her come along on tour.”

“Selena’s acting so crazy that he’s starting to have second thoughts about their relationship. Friends are concerned that it’s only a matter of time before it all ends in tears due to Selena’s self-sabotaging ways.”

The couple first went public with their relationship last month, though In Touch previously divulged that they've been seeing each other in secret for a year — which overlaps with the time The Weeknd spent with his ex-girlfriend Bella Hadid, 20.

“Their relationship deteriorated as they started spending more and more time apart due to work commitments,” an insider said of the Victoria's Secret model. “She began to lose trust when his calls and texts became less frequent. In the back of her mind, she had her suspicions that there was someone else, but little did she know that person [was] Selena!”
