Cabello and Mendes, who put on a steamy display in their "Señorita" music video in late June, have been sparking romance rumors since her split from Matthew Hussey. The singers fueled relationship speculation over the Fourth of July holiday when they were spotted holding hands.

Since that time, Cabello has been spotted at a number of Mendes' concerts, showing her support for her rumored boyfriend.

"Neither of them want to be away from each other," a source recently told E! News. "She has the opportunity to be there with him and she's taking it."

"The timing wasn't right before but it is right right now," the insider continued. "They are going for it without holding back. This step in their relationship is exciting for them both. They haven't wanted to be apart at all. It's 24/7 and all out at this point."
