The 26-year-old singer - who has kept his dignified silence on the model's new romance until now - has lashed out at his ex-lover for striking up a relationship with the former One Direction star two weeks after they went their separate ways.

Joe - who was dating Gigi for five months until they split last November - said: "I think it's interesting that she moved on so quickly, I mean it was definitely very quick."

And, although he's still hurt by how quickly Gigi, 21, moved on, the DNCE frontman finds it hilarious how he's often compared to Zayn, 23, because of their similar style.

Speaking to the Daily Mirror newspaper, he said: "It's comical that I'm compared to him. That dude and I have been compared for years, I think it's just funny."

Meanwhile, the couple - who have been dating for five months - aren't wasting any time taking their romance to the next level as it's thought they're keen to move in together.

A source said: "Zayn wants Gigi to move in with him and she says she now feels 100 per cent ready.

"She loves her New York City apartment and wanted to be sure Zayn was serious before moving to Los Angeles, but she's madly in love with him and can't stand to be apart."
