Emma Roberts relies on her friends to stop her ''wallowing''.

The 21-year-old 'Scream 4' actress reaches out to her inner circle when she's feeling low in a bid to keep her problems in perspective.

She explained: ''If I'm having a really bad day, I always have a girlfriend - or even a guy friend - who I can call.

''They'll listen to me wallow for a minute and then be like, 'Okay, let's stop. Everything's great. Let's figure out how to fix whatever's bothering you'.

''I've gone through times where you're feeling low and you don't reach out to people and you just keep wallowing in that, and I think that's when things turn into a bigger deal than they need to be.

''I think it's important to have people who will pull you out of that, whether it's family or friends.''

Having recently finished work on comedy 'Adult World', Emma says she will start work alongside 22-year-old Liam Hemsworth on 'Empire State' in ''the next month or so.''

She told US Weekly: ''It's really cool - like an 80s heist movie. I'm really excited about that. I play his love interest.''
