The former One Direction member, 22, is said to have pursued the glamour model just days after he broke off his engagement to Little Mix's Perrie Edwards.
According to The Sun, newly-single Zayn sent flirty messages to reality TV star Chloe, although it's not made clear how Zayn knew her.
The newspaper reports that Zayn contacted Chloe on Twitter, asking: "Do you have a boyfriend at the mo?"
However, Ex On The Beach star Chloe, 22, has been dating footballer Jordan Clarke, 23, of League One Scunthorpe for some time.
A friend says: "Chloe was quite shocked by the messages. She knew Zayn had only just split from Perrie and couldn't believe he was already looking elsewhere."
They added: "Chloe is with Jordan, so she was never going to have a fling with Zayn.
"She told him she had been with her boyfriend for a long time. He seemed to accept that, and told her if he hadn't asked he would have ended up being 'rude'.
"His intentions in messaging her were pretty obvious."
Zayn ended his four-year relationship with Perrie allegedly by text last month.
Earlier this week, their new luxury property was put on the market - just two months after they bought it.
Zayn raised eyebrows when he began following Selena Gomez on Twitter, and 'favourited' a sexy shot posted by Kylie Jenner.
He has also been linked to Disney star Zendaya.
If the rumours are true, it sounds like Zayn is trying to enjoy his newfound freedom.
Meanwhile, Perrie has her Little Mix bandmates to support her...
