Zayn Malik is now gigging around the States with One Direction

Zayn Malik didn't care who was looking as he gave new Little Mix girlfriend Perrie Edwards a passionate kiss before he jetted off for One Direction's tour of America this week.

The couple, who were first linked in November after they got chatting when they recorded The X Factor charity single together, shared a big hug and messed around on a scooter in London while they waited for Zayn to be picked up.

'It was a very sweet farewell,' a source tells The Sun.

'You could see they are genuinely really into each other.'

'Just went to see avengers assemble and it was #boring. Good night though! xD @zaynmalik,' Tweeted Perrie.
