Viewers had plenty to say during tonight's instalment of the ITV soap, after Rosie Webster (played by Helen) was seen exercising in her living room.
The actress' cleavage was impossible to miss as she bounced up and down while talking to her on-screen sister Sophie (Brooke Vincent).
Many took to Twitter to comment on her skimpy attire, which consisted of just a bright pink sports bra and skintight leggings.
Rosie's step-father Tim Metcalfe (Joe Duttine) didn't know where to look after he walked on her by accident, before making a swift exit back out of the door.
