The star, 31, is best known in the U.S. for Piranha 3D and her engagement to ex Billy Zane. Brook's boyfriend, rugby player Thom Evans, stayed with her at their home after the two got the news last week. She was due in August; the baby would have been her first child.

Brook first announced her pregnancy via Twitter March 16. A source spoke to the UK's The Sun about Brooks' state.

    "Kelly is absolutely devastated. The baby wasn't planned but she was thrilled and it would have been the best loved little girl in all the world. She has always wanted children and a family and although she hasn't been with Thom long they were so excited about becoming parents. Now all those dreams are shattered and poor Kelly is inconsolable. Thom is being a tower of strength to her but he's grieving too."
