On Wednesday, she shared yet another snap of the couple, this time joined by fellow Made In Chelsea star Spencer Matthews.

Binky and Alex certainly make a super cute couple, though trouble was in the air on Monday night's show thanks to a bit of the green-eyed monster on Binky's part.
Alex used to date none other than Lucy Watson, and Lucy's been making it clear to Binky how much she regrets ditching Alex and hooking up with Spencer instead.
Binky was left to stew... Cue an awkward scene later in the episode!
Binky said to Lucy: "For some reason I feel like it's you being quite patronising. It feels like you were the one reminding me that it was you who said no to him. I don't like anything being brought up like that - it makes it awkward for me."
Yikes! Thankfully, Alex reassured Binky that she's the one for him and from the looks of this snap, all is now well with Binky and her handsome new man. He's even met her mum!
Meanwhile, Cheska has been busy celebrating her mum Karen's birthday.
She tweeted a snap of her and her mum drinking champagne, and said: "HAPPY BIRTHDAY MUMMY!!!!!! Best mum in the WORLD - Huge Love!!!!!!"
What a sweetheart.
