The boys of One Direction have another big event to celebrate this Christmas Eve: their oldest member, Louis Tomlinson, turns 21 today!

The band, along with Louis's longtime girlfriend Eleanor Calder, apparently threw Louis a surprise party at a hotel in the U.K. last week. The bash was black tie and included one hundred close family and friends, according to SugarScape.com.

And no One Direction birthday is ever complete without an epic treat from The Cake Store U.K.. Here's a photo of Louis's sweet birthday cake:

(In our humble opinion, Liam's from July still takes the cake, so to speak.)

In honor of Louis's big day, we've included a slideshow of some of his best fashion moments, from his signature striped shirt and red pants from the groups early days to his more recent coif paired with a sleek suit. Click through photos in the slideshow below.

As for the group's holiday plans, Niall Horan told the Belfast Telegraph: "I'm not really looking for anything for Christmas ... I think we all kind of agree, we're all really looking forward to just going home and, like, spending Christmas with our family and friends, eating a lot, drinking a lot, sleeping a lot, just chilling. General chilling."
