It appears that things are heating up between former One Direction member Zayn Malik and model Gigi Hadid.

Although the two are only rumored to be in a relationship, Hollywood Life reports that the two already spent the night together.

The website further reveals that Hadid was spotted doing the walk of shame the morning after their date.

Hollywood Life also observed that the model was wearing the same jeans from the night of her and Malik’s date and she was still carrying the same purse.

Meanwhile, The Daily Mail reports that a rumored romance between Hadid, 20, and Malik, 22, came into the spotlight when the two were spotted together leaving Justin Bieber’s AMA after-party last Sunday at The Nice Guy in Hollywood.

According to website, the two may have met last August during Kylie Jenner’s 18th birthday party. The Daily Mail points out that Hadid was still with singer Joe Jonas back then.

Rumors of a relationship between Malik and Hadid intensified when the two were spotted again having dinner with Hadid’s sister Bella, E! Online Reports.

E! Online quotes its source in saying:

“Gigi and Zayn couldn’t keep their hands off each other. They were holding hands under the table, whispering in each others’ ears, and Zayn [was] holding Gigi’s leg. Gigi was so attached to him that she even followed Zayn outside to the patio during a smoke break.”

However, although the website’s source suggests that there is something deep going on between the two, another source dismisses the alleged romance.

E! Online reports that their second source revealed that Hadid and Malik are only friends because the model does not want to jump into another relationship so soon.

Whatever the real score between the two may be, they seem to be happy with each other’s company.

In a report by US Weekly, a source is quoted by the magazine in saying:

“They seem equally super into each other, texting each other all the time. They’ve only been hanging out a couple weeks.”

The following weeks will tell whether Hadid and Malik’s relationship will blossom into something deeper.
