Kendall Jenner reportedly spent a lot time flirting with Zayn Malik at sister Kylie's 18th birthday party.

After ending his engagement to fiancée Perrie Edwards in July, the former One Direction member attended the star-studded b-day bash in West Hollywood on Aug. 9. A source revealed to HollywoodLife.com that he was being a "major flirt" with the model.

"He was with her most of the night, laughing a lot, and seemed to feel the most comfortable when he was with her," the source claimed.

"A ton of girls were trying to get Zayn's attention, but he just seemed interested in Kendall," the source continued. "She was smiling and didn't seem to mind Zayn giving her so much attention."

The publication previously reported the British singer seemed to have his eyes set on Kylie, as he favorited a sexy photo of her on Twitter, just days after splitting from Edwards.

"Zayn has a huge crush on Kylie," an insider divulged at the time. "He thinks she is absolutely the sexiest girl in the world and is always checking out her Snapchat videos. He was into her even while he was still with Perrie."

"They met once a while ago through Harry [Styles] and Kendall, but she was young and it was very brief," the insider added. "Since then, she's grown into an incredibly stunning girl, and Zayn has definitely noticed."

However, the teen enjoyed her special day with boyfriend Tyga, who bought her a $320,000 Ferrari. "She and Tyga were joined at the hip," the source added.

Besides, the "Ayo" rapper supposedly does not find the ex-boy bander to be much of a threat and feels rather great about other guys liking his girl.

"If anything it gets Tyga excited that other dudes are crushing on his girl," a source claimed. "He sees how Kanye handles other guys hitting on Kim and he wants to handle it the same."

"He feels like it's a compliment. He wants other guys to be jealous of what he has," the source added. "Zayn can crush on her all he wants cause at the end of the day she comes home to Tyga."
