TV presenter Myleene Klass has given birth to a baby girl called Ava 16/08/2007. The 29-year-old star, who found fame with reality TV band Hear'Say, went into labour shortly after co-hosting The One Show on BBC One on Wednesday. The baby, which weighed in at 5lbs 9oz (2.5kg), arrived at 1345 BST, three-and-a-half weeks early. Klass' fiance Graham Quinn was by her side. "Myleene had a problem-free labour," her spokeswoman said. "Mother and baby are doing well." "Myleene presented The One Show and felt a bit weird on the way home. "She went to the hospital to get checked out and they told her she was in labour. The birth went very smoothly and all is well, but her stint on the show is obviously over for now. "She is looking forward to returning to work after some time off with Ava."
