You are right,she will be 51 on the 22nd May 2009.
So I very much doubt she is pregnant.
Her children are:~
Sons (with Tim Healy): Matthew (born 1991) and Louis Vincent (born 2001)
The only Google references I can find are regarding her 2001 pregnancy.
if anyone watched loose women last week she said her periods are all over the place due to menopause .this was already put to her she said definitely no
