Liam Payne supported One Direction bandmate Louis Tomlinson at the premiere of his new movie, putting on a glamorous display with girlfriend Kate Cassidy.
Louis walked the red carpet and posed for photos with fans at the premiere of his documentary All Of Those Voices, which charts Louis' rise to fame, his feelings after One Direction disbanded in 2016 before touring the world as a solo artist.
Liam was the only one of Louis' former bandmates to attend the do at Leicester Square, and put on a loved up display with girlfriend Kate, a 'US party girl' who he was first reported to be dating in October.
One Direction were catapulted to global stardom in 2010 after Liam, Louis, Harry Styles, Zayn Malik and Niall Horan were put together on The X-Factor, despite auditioning as solo artists.
They all pursued solo careers, with Harry thanking his former bandmates at the BRITs, where he took home a stack of awards, sending fans wild.
Liam and Louis, who didn't pose together, both looked dapper this evening, with Louis rocking an all black suit with a white top underneath, and Liam opting for a white suit jacket, dark shirt and dark trousers.
Partner Kate opted for a one-should black mini dress and knee high boots.
Also at the premiere were Louis' sister Lottie, and her partner, former tennis player Lewis Burton.
In a teaser trailer for documentary, Louis recalled feeling as though he wasn't in control during the early days with One Direction.
He said: "It had always been in my mind that it'd be cool if we weren't just the standard boyband who just got given songs and sang them.
"Maybe we should be writing our own songs, I could feel stuff bubbling for us, I could see that we'd got people's attention.
"I realised that we might be able to make a few of our own decisions and that was the first moment in my One Direction career that I felt ownership of what we were doing."
The dad-of-one went on to explain that he instantly felt more "powerful" than what he may have felt if he'd decided to sing a verse of an early One Direction song.
"All of a sudden, I felt in control again," he added before going on to explain: "The first two and a half years, I just felt like I wasn't in control of myself and certainly not necessarily had an influence on the band."
But while Louis explains he's "proud" of the five lads as "a collective," he admits his proudest moment as an individual member of the group is having the most songwriting credits over the course of their career.
"That makes me feel important to the band and that's all I ever wanted," he gushed.
Louis is credited for some of the group's biggest hits and fan-favourite songs including No Control, Perfect, History, Last First Kiss, Diana, Strong, Through the Dark, Midnight Memories and Night Changes.
