"I am going on holiday to Cape Town to visit some friends with my boyfriend. I'm really excited about it and I can't wait to go trekking up a mountain or two. I've never been there before and it's supposed to be fabulous - I'm going for a month but don't expect that I'll ever want to come back to England!
"I wear trainers all the time and desperately needed to treat myself to a new pair. Trainers are my essential buy, my only tip is to always - without fail - wear socks to avoid embarrassing situations."
