The 16-year-old actress and the 24-year-old actor were joined by their director/writer Jeff Wadlow.
Earlier in the day, Chloe was seen stepping out of her hotel with her older brother Trevor by her side.
“Loved watching #KickAss2 with cast and crew. Movie looks like it cost more than it did ’cause they worked their asses off! Forever grateful,” Jeff tweeted over the weekend.
FYI: Chloe is wearing a Viktor & Rolf suit and shirt, Chanel shoes, and a Repossi ring. She is wearing a Christopher Kane grey lace top out in London.
