Abbey, 27, had been filming for ITV1's This Morning and was snapped as she headed out of the studios in the capital.
The model and mum-of-one, who is married to footballer Peter Crouch, was sporting a tight-fitting long sleeved grey dress and toted a coordinating soft leather handbag.
Abbey was also wearing her blonde hair in big curls and sported lashings of mascara, bronzed cheeks and a natural coloured lipgloss.
Despite her slender frame, Abbey insists she cannot stop eating now she is taking part in Strictly.
In a recent interview with the Daily Express, she said: "I've been trying to eat a lot more over the past few weeks. I mean I eat a lot anyway – there's some myth that I starve myself, but I really don't.
"With all the training you do for Strictly, you're naturally more hungry. You need to eat well otherwise you can't function and you get too tired and feel a bit sick."
