Rosie Huntington-Whiteley finds it hard to make friends.
The 25-year-old model - who is in a relationship with actor Jason Statham - is very "cautious" about trusting people so is wary about striking up a bond with new acquaintances.
She said: "It takes me a long time to make friends, only because I travel a lot and I don't trust easily.
"I'm cautious, that's just something I've learnt. I've been burnt in many ways and you're cautious about the people you'll allow into your life and who you invest time in."
Rosie's closest friend, Maddie, is training to be a teacher and the 'Transformers: Dark of the Moon' star enjoys spending time with someone outside of the showbiz world.
She told Britain's Elle magazine: "She is not connected to this industry in any way, shape or form, she's such a breath of fresh air."
Most of Rosie's friends are people she has known since childhood.
Speaking about her pals, she said "They knew me first when we were jumping in bushes on the way home from a nightclub, aged 14."
