5. Louis is the oldest member of One Direction and he was born on Christmas Eve! He's 20-years-old. According to a lot of fan sites out there, he totally doesn't like being the oldest dude in the band either!

4. Like Niall Horan, Zayn Malik and Harry Styles, Louis has really awesome taste in music. His favorite band is The Fray and he sang The Plain White T's "Hey there Delilah" at his X-Factor audition (peep that below!). It's also been said that his idol is singer Robbie Williams.



And he likes one of our favorites too...Ed Sheeran!

3. He only has sisters! They always say that the best type of guy to date is one with a sister...imagine dating him, he has four!

2. He's got a bromance with band mate Harry Styles. In a recent interview with Hollywood Life, Louis explained that the two of them are pretty close and that sometimes fans dig too deep and think they're in a romance!
