The trio posed separately on the red carpet before dining together at the charity event, which raises money for orphans and vulnerable children around the world.
The dress code was rather subdued, with Katy looking classy with a touch of whimsy in a dotted skirt and black turtleneck.
The singer's makeup was also less elaborate than usual, with only a swipe of burgundy on her lips.
Rob and his fiancée also kept it simple in a black suit and white jumpsuit, respectively.
Are you loving this threesome or what???
