Charlize Theron is preparing to join the Hollywood mums club after revealing she's ready to start a family with partner Stuart Townsend. The Oscar-winning actress, who has started referring to the Irishman as her 'husband' in interviews, has hinted that she could well become the next celebrity mother. Theron tells In Touch magazine, "I've been thinking about becoming a mom for a couple of years now. My biological clock is ticking, but it hasn't gone off yet. "I couldn't hope for my career to be going any better, and I have found the great love of my life in my relationship, so I think we're ready to start having kids running around the house. "I'm ready to take on the responsibility of motherhood."
