The mum-of-two was in the studio today (13 February) modelling the brand's latest lingerie range, but it seems she got a bit distracted, And who can blame her?!
Littlewoods staff had laid on an amazing selection of yummy treats for the occasion, including hunks of rocky road and chocolate cakes topped with pink icing hearts.
Myleene literally couldn't believe her eyes and was quick to tuck in after posing for a picture, which she then posted to Instagram.
The classical musician, who was dressed in a white robe, jokingly commented: "I'm supposed to be shooting lingerie. @littlewoods have self sabotaged!"
Meanwhile, earlier in the day Myleene was joined in her lunch break by her youngest daughter Hero. The cute pair were captured in another photo while having a chat.
Myleene told her Instagram followers: "Late lunch and deep discussion with one of my fav girls at today's @littlewoods shoot. #perfect."
