Just hours after McFly and Busted announced that they will be teaming up to go on tour together in 2014, the six stars of the bands were seen celebrating their exciting news at The Hunger Games: Catching Fire premiere in the capital.
McFly's Harry Judd, Dougie Poynter, Tom Fletcher and Danny Jones joined Busted's Matt Willis and James Bourne to bond at Monday night's red carpet event (11 November) and the boys even decided to prove just how serious their new supergroup is by each dressing in the same colour.
In various black ensembles, the six singers appeared elated to be out on the town with one another and we have to admit, they look pretty good together!
While Matt and Dougie donned black fedora hats to give their outfits an edge, Tom and James decided to ditch the smart shoes that their bandmates were wearing in favour of brightly coloured trainers.
Following on from their red carpet debut (and forming a human pyramid in front of all the cameras!), McBusted then sat down to watch the latest Hunger Games instalment and later rounded off their night by stopping by the film's after party.
With their jam packed first day as a supergroup over, the boys expressed how much fun they'd had over Twitter.
Matt wrote: "Whole day hanging out with @McBusted all day and night! Love being in this band already! #McBusted", while Matt tweeted: "That was an insane day .... INSANE."
The guys also posed for a some candid snaps together, keeping their fans updated with their McBusted exploits.
It's safe to say we're obsessed with them and it's only been 24 hours!
McBusted are set to perform on BBC's Children In Need this Friday (15 November), the same day as their 2014 tour tickets go on sale.
