This is so sad.
After wrapping up their whirlwind Up All Night US tour, it looks like One Direction's Louis Tomlinson is happy to be reunited with his girlfriend, Eleanor Calder!
The two were caught kissing and canoodling ALL over the airport in Nice, France, yesterday!
Check out a pic of Louis gettin' some airport action (above)!!
Behave, you two! LOLz!
We're sure they got some celebrating in for Louis' two-year anniversary of him getting through on The X Factor UK!!
