Is Gigi Hadid trying to send Zayn Malik a message?

Just one day after rumors swirled that the 21-year-old model split from the former One Directioner, Hadid stepped out to host the Maybelline New York Beauty Bash at the Line Hotel in Los Angeles on Friday.

Throughout the night, Hadid took over the beauty brand's Snapchat, and in one of the videos, she lip synced to her rumored ex's hit song, "Pillowtalk."

An eyewitness tells ET that the blond beauty went up to the DJ booth, where it appeared that Hadid herself requested the song! Once it started playing, she reportedly insisted that the DJ turn it up twice as loud.

Judging from the post, Hadid -- who has yet to officially comment on the breakup -- either confirmed that she's totally OK with the split and there’s no bad blood between her and Malik, or she's implying that the rumors are false.

Fans of the couple who saw the Snapchat were just as confused, taking to Twitter to express their opinions.

"It's her way of saying she will always love Zayn and she still thinks of him," one user wrote. Another tweeted, "They need to not play with my emotions!'

But it gets even juicier!

Hadid was spotted chatting with Alli Simpson, the 18-year-old sister of another one of her ex-boyfriends, Cody Simpson, whom she dated on and off from 2013 to 2015.
