The Street's Fiz is struggling after her recent diet success

Coronation Street actress Jennie McAlpine seems to have broken her diet.

Earlier this year the 24-year-old slimmed from 13st to 10½st.

She’s never set out to be super-thin and shuns the gym, but she was snapped looking plumper as she arrived on set last week.

‘She lost weight playing on her Nintendo Wii and walking to work, as well as things like swapping burgers for salads. There was no tough training schedule or starvation diet,’ a source tells Now.

‘But since she returned from filming the Coronation Street Christmas DVD in South Africa, her efforts to keep up a healthy regime have gone to pot.

‘The change in routine has thrown her and as it gets colder it’s easier to tuck into the stodge at the Corrie canteen than think carefully about what she eats.’
