The pretty blonde, 31, was snapped revealing acres of her cleavage in a plunging blue peplum dress in London earlier today.
The Mrs Biggs star was spotted as she arrived at ITV's studios in the capital to film a slot on This Morning.
Busty Sheridan, who is co-hosting the Olivier Awards on Sunday, wore her blonde hair up and accessorised her figure-hugging frock with a pair of gold hoop earrings and black peep-toe heels.
And the blonde, who is a two-time Olivier Award winner herself, looked every inch the star as she later headed off in a pair of designer shades.
Read an exclusive interview with Sheridan in this Saturday's TV Magazine.
