1D have just wrapped the Aussie leg of their worldwide 'Where We Are' tour and were supported Down Under by fellow Brit pop stars McBusted.
Last night, McBusted singer Tom Fletcher shared a picture of himself, his bandmates and One Direction on Instagram, which was taken following one of their stadium gigs.
Giving the ultimate super-group a new name, Tom commented: "McBusterection? Thanks for having us in Oz lads, see you in Europe!"
McBusted is formed of both noughties groups McFly and Busted so, combined with the One Direction lads, this really is the best mash-up possible!
Now their Australian leg is completed, 1D's Harry Styles, Niall Horan, Zayn Malik, Liam Payne and Louis Tomlinson will be heading to Japan.
Waving goodbye to McBusted, the former X Factor stars shared Tom's picture on their official Twitter account and said: "Backstage with @mcbusted in Aus. The guys are looking forward to doing it all again in Europe! #OnTheRoadAgain2015."
McBusted were only announced as one of the group's support acts last month and, following the news, Niall tweeted: "What dreams are made of, touring! and @mcbusted tour with you! I've deffo done a little wee with the excited of it all" Err, nice!
