Katy Perry and Adele shared a diva-packed selfie on Wednesday.

“…And on the 2nd LDN show the Queen graced me with her presence,” wrote Perry, accompanied by the shot of the two star singers (see below).

The “Roar” pop star is currently on her Prismatic World Tour, and her London performance dazzled Adele.

“Katy Perry was supreme tonight!” she tweeted after the show.

Adele, whose son is a year and a half old, has been mostly off the radar since receiving a medal from Prince Charles back in December.

But she apparently couldn’t let Perry pass through town without a visit.
