Hailey decided to lend a helping hand in January 2015 when she gave Justin her hair-tie right off her wrist!
They might not have been together when this photo was taken in June 2015, but they sure did look good together!
In this photo from May 2015, the "Baby" singer rocked a fake mustache while the model sweetly posed behind him.
In December 2014, Kendall Jenner joined Justin and Hailey for a Nerf gun night!
Earlier in December, the A-lister took to Instagram to shut down any dating speculation between him and Hailey. "People are crazy. I'm super single and this is my good friend u would know otherwise," he wrote. Hmmmmm. Foreshadowing much?
Back in 2014, Hailey and Justin were cool and coordinated, rocking LA Clippers gear as they hung out together as friends.
