Gigi Hadid had broken up with her former boyfriend, Joe Jonas, earlier this month, and it seems there's no stopping the model from moving on too fast. On Monday, Gigi was seen arriving at the LAX airport after she reportedly spent a romantic weekend in London with her new beau, Zayn Malik.

Hadid is back home to spend the holidays with her mother, "Real Housewives of Beverly Hills" star, Yolanda Foster. The Models.com's model of the year was seen in high spirits as she  stepped out of the airport. According to Daily Mail, Hadid spent time with the former One Direction crooner right after her photo shoot in London. Upon arrival at Malik's home, the model tried to be incognito as she covered her face with her hand.

On Sunday, Hadid and Malik posted a steamy selfie where they were seen cheek-to-cheek. Their latest Instagram post gathered both positive and negative comments, with some sympathizing with Perrie Edwards, Malik's ex.

"They've only been dating for a while, but Gigi and Zayn are already very serious about each other," a Hollywood Life's source said. "So serious in fact, that Zayn is already looking forward to introducing Gigi to his family and friends over the holidays. No wonder Perrie is so crushed!"

Hadid and the 22-year-old British hunk were first spotted being cozy with each other last month. Since then, they have been inseparable over the recent weeks.

Meanwhile, it was only also last month when the Sports Illustrated model split with Jonas due to their busy schedule. According to multiple reports, the two ended things with no drama, and they have remained friends.

On the other hand, as the romance of Hadid and Malik heats up, Edwards is reportedly still hurting. Perrie is allegedly still struggling with her and her fiancee's split, and it is more difficult to move on now, seeing Malik has a new supermodel girlfriend.

Meanwhile, things are going really fast for Hadid and the former "X Factor" contestant as they are now apparently planning to spend the holidays together, Tribune reports.

"Gigi has already invited Zayn to celebrate Christmas with her family. He's become very close with Gigi's mother and sister, which is nice for Zayn since he didn't really have anyone when he moved here,"  a source said.
