Lucy sends temperatures soaring

She spends a lot of her time working out in the gym with her PT.
So it's no surprise that former TOWIE babe Lucy Mecklenburgh has a killer figure.
A BTS snap of her at a swimwear shoot leaked at the weekend.
And the reality-star-turned-fitness-guru looks sensational.

Wearing nothing but a tiny white dotty swimsuit and a black fluffy fur stole, Lucy shows off her killer pins and pert bottom as she poses while holding a coffee cup.
The brunette stars smiles proudly as she works the camera.
Louis Smith is one lucky boy.
The TOWIE stunner, whose workout videos and diets promise girls their dream body, almost broke the internet last week when she posted a photo of herself working out.

The cracking brunette posted one sizzling shot of her on the weights revealing her tiny waist and perfectly round bum.
And just to show it wasn't a one-off she posted a bikini shot of her gravity defying shot.
And we reckon there's no easy shortcut to such perky buns.
