But how did you get that bum, Lucy Mecklenburgh?

Ooer, Lucy Mecklenburgh – the former TOWIE star has had us all vowing to up our squat count since posting a saucy snap of her pert posterior on Instagram, which surely has her long-distance boyfriend Louis Smith booking his plane ticket home!

The toned 24-year-old, who last week hiked Mount Kilimanjaro in aid of the Cystic Fibrosis Trust, wore a risque ensemble of black lacy underwear, paired with stockings and suspenders for the photograph. She added the sassy caption: ‘BEHIND the scenes.’ Clearly all that uphill climbing paid off, Lucy, because you are looking fabulous!

She followed up with a photo of a note reading ‘I miss you’ with the cute caption ‘It’s been a month only a couple of days to go!!! #longdistancerelationship’. We bet gymnast boyfriend Louis can’t stop thinking about her while he’s competing at the Glasgow Championships. The couple first met at BBC gymnastics show Tumble in August 2014, but only got together the following December after splitting from their respective flames.

Although Lucy has since deleted the underwear snap (perhaps to send exclusively in a private message to her lucky boyfriend?), beady-eyed fans have already responded on Twitter, with one user writing: ‘New @instagram shot of the gorgeous @lucy_meck <3.’

But did the Essex beauty post the photograph accidentally? Or did she just have second thoughts about sharing the sexy look? Either way, we think it’s a great advertisement for her new workout website, Results With Lucy…whatever she’s doing, we want her exercise secrets!
