For the record, Louis Tomlinson and Harry Styles are NOT an item.
But the former is celebrating a milestone today, as Tomlinson will be free to down as much egg nog and champagne as he wants on Christmas: the One Direction singer is now 21 years old!
Tomlinson is the oldest member of the wildly popular British boy band, besting Liam Payne, Zayn Malik and Niall Horan by two years.
Look for these young artists to present fans with a special gift early in the new year: the official music video for "Kiss You," the third single from their latest album, which was penned by Ed Sheeran.
Among other celebrities celebrating a birthday on December 24: Ryan Seacrest is 38, Stephenie Meyer turns 39 and Ricky Martin can dance the night away as a 41-year old.
