Vanessa White knows she will gain weight during the Christmas holidays.

The Saturdays beauty is usually health conscious throughout the year, but plans a big blowout next month and will indulge in all her favourite festive treats over the holiday period.

She said: ''I'll put on loads of weight over Christmas. I'll be on the wine, turkey, pudding - everything!''

While she is planning a short indulgence, Vanessa, 24, will surely lose the holiday weight quickly as she is a keen gym enthusiast and admits she feels ''guilty'' if she doesn't work out on a regular basis.

She added: ''I love the gym, but sometimes I feel sick and want to run away from my trainer!

''If I don't go to the gym, I feel guilty. It's paid off ... I look a lot more toned.''

Meanwhile, it appears Vanessa - who was known as the biggest night owl in The Saturdays - will have a much quieter 2014 after giving up partying.

She previously said: ''I'd been partying way too much, not taking care of myself and I felt rubbish. We're all very honest with one another and we will sit each other down and say, 'This is getting out of control.'

''If I hadn't had them, it would have been so easy to have gone off the rails and kept up the partying until it became a problem. You need people around you to say, 'Right, this is too much now,' and fortunately, I have that.''
