Ouch! While performing with One Direction in Portugal last night (June 13), Liam Payne accidentally tripped and hurt his knee, leaving the singer in pain but determined to continue the show. And as it turns out, being unable to walk proved to be no problem for Liam -- thanks to bandmates Niall Horan and Zayn Malik, who literally carried him onto the stage to perform 'You and I.' Sigh!

As the band's guitarist played the opening notes to the romantic ballad, Niall and Zayn emerged onstage, carrying and supporting Liam, who had each of his arms wrapped around his bandmates' shoulders. So sweet! The guys carefully carried Liam down a ramp and onto a lower section of the stage, as the audience erupted into screams and chants of "Liam! Liam!" before the guys began the heart-melting tune.
