Kate Upton hates reading rumours about herself.

The 22-year-old bombshell says her mother is constantly scolding her about untrue stories she reads in the press and it drives her ''crazy'' that her family have to question her actions.

She told VOGUE.co.uk: ''Reading things about myself that aren't true drives me crazy! I've managed to block it out, but my family really hasn't - so they'll read about me and then call me up saying, 'Are you alright? I saw this happened' and my mum will call and say, 'Well, I saw you went to Vegas, when you could have come to the family reunion...' and I'm like, 'Mum, I swear, I'm in Europe!' It's insane!''

Despite always looking like a pro on the red carpet, the Sports Illustrated beauty admits she sometimes feels infuriated by the photographers' demands.

Kate said: ''I enjoy the red carpet for the first 10 minutes and then I'm like, 'Alright....let's go'. Sometimes the photographers get really bossy, like 'blow a kiss!', 'smile!' and I think, 'You don't know Mr, you're not a model! This outfit is meant to be fierce, it doesn't go with smiling!'

''When I first did red carpets, I used to listen and do what they said - but now I don't.''

'The Other Woman' actress has found a secret weapon to combat nerves - flashing a killer smile.

She revealed: ''My mother always taught me that smiling when you walk into a room is the best beauty secret, so if I'm nervous when I walk in I just smile, and I think everyone warms to you quicker that way.

''Sometimes people look stern when I come on set, just because they're concentrating or getting ready for their day, but I'll chat and smile and finally I break them down!''
