Frankie's back! First job? Proving Una's preggo

Hurrah! To quote Atomic Kitten (retro), The Saturday's are "whole again" as Frankie Sandford finally returns from rehab.

Frankie posted this cute Twitpic of her measuring bandmate Una Healy's little baby bump with a yellow tape measure on Twitter yesterday. She wrote: "I've been very impatient for Unas bump to show. I've come back and it's finally here! The Sats baby is growing!!!!! :)"

The singer, who's dating footballer Wayne Bridge, has been absent from the band for a couple months, apparently under doctors orders.

A spokesperson insisted that her stint in rehab has nothing to do with "drugs, alcohol or plastic surgery".

We're glad you're feeling better, Frankie!
