'Coronation Street's Helen Flanagan has been scoffing so much of the greasy grub from the soap's canteen since her return that her belly is now bulging over her jeans.

The 26-year-old actress has only just reprised her role as mega bitch Rosie Webster in the long-running show but she has admitted the costume department will need to get her alter-ego some bigger clothes because she's piled on the pounds recently thanks to the wide variety of calorific treats on offer backstage for the talented cast.

She's quoted by the Daily Star newspaper as saying: "I'm obsessed with the food in the 'Coronation Street' canteen - it's one of the best things about being back.

"My jeans have already got too tight for me in those few weeks [since she's been back]. I'll have to ask them to get Rosie's clothes the next size up. I love it."

And the brunette beauty - who has 15-month-old daughter Matilda with her long-term partner Scott Sinclair - isn't the only cast member who can't resist the canteen grub.

Brooke Vincent - who plays Helen's on-screen sister Sophie Webster in the soap - recently admitted that she loves the breakfast so much that she often pops into the studio on her day off just so that she can get tuck into the delicious spread.

She explained at the time: "People are gonna laugh at me now. I love my work. For instance yesterday I wasn't at work but I popped in for my breakfast because we get free breakfast and you sit and have a chat with everyone.

"I was close, so I nipped in. You can literally nip in at any time of the day. Three meals a day. Chewing gum, creme eggs, you can take the lot."
