One Direction star Zayn Malik has been acting strangely recently - and we're worried it's because he's got a new girl.

The 19-year-old singer - who's been linked to Little Mix's Perrie Edwards and Hollyoaks actress Stephanie Davies, both 18 - has hinted twice in as many weeks that he's no longer single.

'The awkward moment when some1 is staring at your girlfriends breasts ! Aha :) x,' Zayn Tweeted cryptically during the boys' US trip.

And now he's aroused our suspicions even further by suggesting that he might have a date lined up for 14 February. 

'I'm going to stick to my mysterious role,' he tells Cambio. 'Maybe I have a Valentine, maybe I don't.'

Who do you reckon is the lucky lady?
