Harry, Niall and Liam donned their best suits to attend the Class of '92 West End premiere and after party at London club Chakana.
Harry and Niall were flying solo for the night while Liam was joined by his girlfriend Sophia Smith.
She looked stunning with her long brunette locks flowing, her legs on show and a simple black dress.
Liam and Sophia have been mates since they attended the same school together in Wolverhampton, and Liam confirmed that they were in a relationship in August.
The boys were clearly in a celebratory mood.
As well as getting to hang out with football legends like David Beckham at the Class of '92 premiere, their album Midnight Memories has become the fastest selling album of the year.
Now that's an achievement!
After their night out, Niall Tweeted: "Great night last night at the @classof92film. Great film!"
