Lucy busted her boyfriend after he'd slipped into one of her jumpers and decided to share the snap online.
James looked less-than-pleased to have been caught in the ladylike jumper, wrinkling up his face and frowning as Lucy merrily snapped away.
We're loving the fact that James / Lucy's jumper read: "Beautiful little fool." Looking good, James!
Lucy captioned the shot: "Caught wearing my clothes."
Lucy and her super hot co-star James have been dating since the last series of Made In Chelsea and things are obviously going well for the couple. He jetted out to Los Angeles early to spend time with his girl as the cast filmed Made In Chelsea: LA.
And earlier this week, Lucy gushed on Twitter: "Why is my boyfriend so wise."
In early September, the couple took part in Scott Mills' Innuendo Bingo on Radio 1 and Lucy shared a shot of the pair heading to the radio station in matching outfits, adding: "Matchy."
What with their matching wardrobes, Lucy cooing about James being wise and his new penchant for borrowing her stuff, we reckon this MIC romance could go the distance!
