Supermodel Rachel Hunter is terrified she is running out of time to have another child, as she still hasn't found the right man.

The leggy 36-year-old already has two children RENEE, 13, and LIAM, 11, by estranged husband rock star Rod Stewart, but she is desperate for another chance at motherhood before she hits 40 - and her biological clock is ticking.

She muses, "I still haven't found the man of my dreams but I hope he's still out there.

"I'd love to have more children but I've said to myself that 40 is the cut-off point to have another baby."
