Nick Jonas and Patrick Schwarzenegger celebrated their birthday at the same venue on Friday.

Nick, who was dressed in a navy striped blazer and white T-shirt, was joined by his girlfriend Olivia Culpo as he partied the night away with his close friends.

Taking to his Instagram account after the celebration, he posted a picture of his huge birthday cake, which was made to look like it was made out of televisions, and thanked the venue for hosting his party.

He wrote: "Birthday in #Vegas thanks #Hakkasan for the Bday love @oliviaculpo (sic)."

Meanwhile, Patrick, the son of Arnold Schwarzenegger, celebrated his birthday with a smaller cake, but still looked impressed with the calorific treat, which had been made out of blue icing with a big "21"

stuck on the top, as he grinned for the camera.

The hunk even had a go at spinning some tunes on the decks in the DJ booth as he attempted to keep his celebrations low-key with a number of his pals.

However, the actor admitted the next day that he was suffering as a result of the previous wild antics.

Taking to his Twitter account on Saturday, he tweeted: "Woahhhh.

Feeling it today. (sic)."
