Former Atomic Kitten singer Jenny Frost has become a mother for the first time. The 29-year-old - who replaced Kerry Katona in the girl band - and partner Dominic Thrupp have welcomed a boy. Thrupp says, "We haven't picked a name yet. We're just really pleased and excited. "Jen is knackered. I'm going to lavish her with champagne when she can drink again."
