The former TOWIE star is among the celebrities competing in the gymnastics-themed show later this year, and has been hard at work in the gym honing her skills - and she has the bruises to prove it!
Lucy shared a photo to Instagram last night showing some nasty looking bruises on her leg. "No Pain, No Gain!!!" she told fans. "Serious Bruisage! #Tumble #Training."
Tumble will see ten celebrities showing off their best gymnastics moves under the tutelage of professionals including Olympic medallist Louis Smith.
Other stars competing include Girls Aloud's Sarah Harding, Steps singer Ian 'H' Watkins and Sugababe Amelle Berrabah.
"I'm scared, nervous and more excited than I can describe about Tumble!" said Lucy. "To have the opportunity to learn a new skill is a dream come true for me. Although I'm sure I'll be falling over a lot before then!"
While gymnastics may be a completely new sport for Lucy, she is known for her love of working out and staying fit.
The gorgeous star left TOWIE to focus on other projects including her successful Results With Lucy business, which offers nutrition and exercise advice.
