It's a tribute to Hailey! Justin Bieber and Ed Sheeran's collab "I Don't Care" is all about how a lady helps his man get through his anxiety and how she makes everything better when they're alone. So sweet!

Here's a sample of the lyrics, "With all these people all around / I’m crippled with anxiety / But I’m told it’s where we’re supposed to be / You know what? It’s kinda crazy ‘cause I really don’t mind / And you make it better like that." Sounds like Bieber's leaning HARD on his new wife ... and we pretty much knew that already. Hailey Baldwin's a godsend for Justin.

Check this: "'Cause I don’t care when I’m with my baby, yeah / All the bad things disappear,” the Grammy winners croon during the chorus. “Yeah, you’re making me feel like maybe I am somebody / I can deal with the bad nights when I’m with my baby, yeah."

If this doesn't make Hailey happy, we don't know what will! Clearly the couple has struggled with Justin's ups and downs since they were married last year, but kudos to them for getting help and sticking it out. It seems like Hails is really JUST what Justin needs.
