5 Seconds of Summer are super grateful to the guys of One Direction! The Aussie band have been supporting 1D on the U.K. and North American legs of their Where We Are tour, and at their recent Pheonix stop, they showed their love for the guys -- through song!

When Luke, Calum, Michael and Ashton took the stage on Sept. 16, they surprised the audience (and the band!) with their adorable ode to One Direction, singing:

"Thank you Niall, Louis and Harry, Zayn and Liam, too," the band belted out as the crowd screamed excitedly. "They've had us on this tour for a long time and now they don't wanna get rid of us."

Now, all we need is for 1D to respond to 5SOS through song and our lives will be made. They have less than a month left of tour (the last show is on Oct. 5 in Miami) so we'll just be (not so) patiently waiting for One Direction to return the favor. C'mon guys!

Watch 5SOS' swoon-worthy ode to One Direction in the video above.
