Connor Cruise celebrated turning 18 with his sister Isabella having a DJ gig and taking to the decks at the Boujis nightclub in South Kensington

Connor Cruise, Tom Cruise’s son, celebrated turning 18 yesterday having a DJ gig and taking to the decks at the trendy Boujis nightclub in South Kensington, London.

Connor Cruise had his biggest fan there to watch him – in the form of big sister Isabella, 20.

Connor and Isabella Cruise, who have always had a close relationship, were adopted by Tom Cruise and second wife Nicole Kidman.

He was dressed casually to celebrate his birthday and wore a red plaid shirt along with black trousers and matching lace-up shoes.

Joined by a group of friends in the club they drank Grey Goose Vodka and had some crack baby shots, which went down well.

Connor and Isabella Cruise both wrapped up warm to combat the cold weather, with Connor in a simple black coat and his sister sporting a khaki parka.

Isabella Cruise also wore a simple black tank top, matching skinny jeans tucked into oxblood Doc Martens and a navy beanie hat to keep her head warm.

Connor Cruise decided to pace himself before the evening’s festivities and sensibly squeezed a disco nap in.

He tweeted: “About to take a pregame nap cause I’m old before I head to @boujis for some fun.”

The comment was met with many of his Twitter followers chiding the teen for calling himself “old”, and some suggesting that his famous father was a good way ahead of him at 50.

Connor Cruise later added: “This debate over age is hilarious. All I can say is you are as young and as old as you act. In regards to my pops all I can say is #Ironman.”

Not seen today were either of the pair’s parents, who are both currently in Los Angeles.

Nicole Kidman recently said of her son and daughter in an interview with The Hollywood Reporter: “I have two children who are Scientologists – Connor and Isabella – and I utterly respect their beliefs.”
