Welsh singer Charlotte Church has sparked speculation she is pregnant after she celebrated Ashlee Simpson's 22nd birthday in London by drinking only water. The Voice Of An Angel soprano, who is dating Welsh rugby ace Gavin Henson, also looked to be carrying more weight than usual on her tummy at the bash this week (ends15OCT06), according to British newspaper the Daily Star. A source says, "Everybody at the party was whispering about the rumours. It just isn't like Charlotte to party all night without alcohol."
