Last night, the erstwhile Lady Mary went to some BFI thing for Christopher Nolan, and as it was Valentine’s Day, she wore this very dishy simple little red number, and brought along Jasper Waller-Bridge, who is both Phoebe’s brother and Michelle’s newish husband, whom she wed at (we are not making this up) Slut’s Hole last September. To all these things we say HOORAY. Especially how blissed out they look? Young love!
