Socialite Paris Hilton is getting her body in shape to have children as soon as next year (08). The hotel heiress has begun a rigorous regime of pilates, canyon climbing and horse riding to accompany her gym training. Despite being single, Hilton is adamant she will become a mother next year (08), after being influenced by best pal Nicole Richie's pregnancy. She says, "I just started working out and it feels great. It gives me so much energy. I want kids next year, so I've got to get my body ready."
