Joe Jonas was apparently angry that ex-girlfriend Gigi Hadid moved on so quickly to Zayn Malik just months after their split.

E! News allegedly talked to a source who claimed that Joe Jonas was "a bit upset" about how fast Gigi Hadid went public with her relationship with Zayn Malik.

"He still has feelings for Gigi that won't just disappear overnight," the alleged source claimed. "They did love each other and he still has a love for Gigi. He is not looking to rush into another relationship though just yet."

Right now, Joe Jonas is not looking for any rebound fling just to show up Gigi Hadid for dating Zayn Malik, the ex-fiance of Little Mix singer Perrie Edwards.

"He is focusing on his music and new projects that are in the works. He has some great friends and family around so, like anything, he knows his feelings for Gigi will pass with time," the article claimed. "He has many options of women, but he is a pretty picky guy."

A week ago, Zayn Malik and Gigi Hadid went public with their relationship when they stepped out of The Nice Guy club in LA with their hands interlocked.

"Since they were first linked together in early November 2015, Gigi and Zayn haven't been shy about hiding their affection for one another," Hollywood Life.

"But they're not flaunting it, either," it added. "As the couple strolled out of The Nice Guy, they were met with a flurry of photographers and flashing lightbulbs. But it didn't deter them from calmly making their way to their waiting vehicle, clutching each other's hands the whole time."

Apparently, Zayn Malik "has had his eye on Gigi for a while, he's absolutely smitten with her good looks," said Hollywood Life. "He was just waiting for the right moment," or until the model has broken up with Joe Jonas.
