Louis Tomlinson is going to be turning 21 on December 24th!
But Lou couldn't wait until Monday to celebrate, so he had a party on December 15th with a bunch of his friends.
They went to a hotel in Nottinghamshire, and all his One Direction bandmates were there to support him.
His girlfriend Eleanor Calder was there too of course! Louis also invited a bunch of family members and close friends for a formal party.
He got a huge cake and had over 100 guests there to celebrate with him.
Happy early birthday, Louis!
