LOS ANGELES (ES)Mila Kunis finds it ''hard'' to trust others. The 'Ted' actress - who is believed to be in a relationship with Ashton Kutcher - is trying to shrug off her cautious side and become ''more fun'' and ''more open'' in her life because she struggles to fully rely on people. She said: ''I'm trying to be less guarded and more open. I find it hard to trust people. There's a side to me that's very cautious and suspicious.

But I'm gradually feeling a little more secure about who I am and enjoying everything that's been happening to me.”
