Justin Bieber had a wild party night with Brooklyn Beckham in London.

The 23-year-old singer probably wanted to do something good for the son of David and Victoria Beckham, whose new photography book 'What I See' is heavily criticized. To get his mood back on track, Justin invited him to the British Summer Time festival in Hyde Park before the two moved around the houses together. A confidant told The Sun newspaper: "Brooklyn had a hard week after its book was heavily criticized, so Justin wrote to him." The two had also been eating together - first in the 'Ours' restaurant in Kensington and then in the 'Chiltern Firehouse'. Justin, who was "absolutely in a party mood", ended up with his buddy in the 'Tape' night club in Mayfair. "Justin took off his t-shirt at some point, swung it through the air and just danced in his pants and with his hat on his head," the insider describes the party night of the two.

Bieber is just one of Beckham's hip party friends. In the radio show 'Capital London Breakfast', the eldest son of the Beckhams recently told of fun nights with singer Ed Sheeran. The 18-year-old told the moderator Roman Kemp: "Ed is funny. I was with him in a couple of pubs. At one time we talked almost only about tattoos because I never saw his ... they are always covered." After a while, Brooklyn got to see her because Ed took off "his t-shirt in the middle of the pub" - just like Justin in the club last Saturday.
