Coronation Street star is a guest on Lorraine Kelly's breakfast show

Catherine Tyldesley has a great understanding of what clothes suit her sexy hourglass figure.

The actress – who’s slimmed down from a size 22 to a size 10 – wowed when she arrived at the ITV studios earlier in a flirty floral frock.

Cut in a flattering A-line shape, the knee-skimming number hugged Catherine’s sexy toned waist.

The Coronation Street star styled her 50s-inspired dress with white courts and wore her blonde hair in loose waves.

Catherine, 30, was at the London venue to talk about the importance of eating a healthy diet with Lorraine Kelly.

Fab to see @Cath_Tyldesley on @reallorraine talking sense about nutrition,’ Tweeted one fan after watching the interview.

Beautiful woman and a fabulous role model.’

Another added: ‘Great to see @Cath_Tyldesley giving viewers the real nutrition advice that helped her, rather than plugging a fad diet or an exercise DVD. 👍
