Gigi Hadid and Zayn Malik have made it official on social media. The pair, who first sparked dating rumors last month, shared their first couple picture on Instagram on Sunday, Dec. 20, to the delight of fans.

The photo, which was posted in the former One Direction member's account, shows Malik with his eyes closed while the model holds him close to her and has her hand on his face. The shot was uploaded without a caption, but the photo, which has been liked more than 750,000 times since it was posted, was deemed "perfect" by many of Malik's fans.

Hadid was spotted visiting the singer at his north London home. According to the Daily Mail, the 20-year-old tried to go incognito but was recognized anyway by fans and the paparazzi.

The website published some photos of Hadid arriving at Malik's home. In the shots, she is wearing a grey crop top under a grey coat, jeans, and crocodile-print boots. The website claims that the star arrived at Malik's house after leaving a photo shoot in London.

A source told Hollywoodlife that the pair's relationship is getting more serious and Hadid is said to be very happy with the British singer.

"When they're not together, Zayn texts her and she can't wait to text back, and they're always communicating 24/7," said a source to the website. The insider said that while her friends think that the model should "not throw herself into relationship after relationship," Hadid is happy and ignoring what her friends are saying.

Hadid split with Joe Jonas last month. Meanwhile, Malik ended his engagement with Perrie Edwards last August. The two appeared to confirm the dating rumors last month as they were spotted holding hands while leaving The Nice Guy in West Hollywood.
