One Direction's Louis Tomlinson And Girlfriend Eleanor Calder Celebrate One-Year Anniversary

His buddy and One Direction bandmate Liam Payne might have recently gotten his heart broken after his split from girlfriend Danielle Peazer, but Louis Tomlinson, 20, is making sure he does everything he can to solidify his relationship with his own lucky lady, Eleanor Jane Calder, 20, a second-year student of politics and sociology at the University of Manchester.

Tomlinson certainly seems on his way to lasting love, as he and Calder celebrated their one-year anniversary together on Saturday, reports EntertainmentWise.com. And the duo don't have any trouble expressing their feelings for the whole world to hear, either.

"What a great year together @EleanorJCalder 🙂 Love you!!!!" Tomlinson tweeted, to which Calder replied, "Happy 1 year! I love yoouuu xx."

Tomlinson has opened up about how great Calder is before, even in light of the long-distance issue that comes with him being … well, a young superstar. "We both trust each other — I spend a lot of time out of the country on tour. She often flies out so I see her a lot. I think the key to a good relationship is being best friends too. I spend more time with her and the band than I do with anyone else. She's really great."

This weekend also worked out for Tomlinson and the other membes of One Direction, which includes Payne, Harry Styles, Niall Horan and Zayn Malik, as their single, "Little Things," hit number one, as did their LP, "Take Me Home."
