It's been two years since Louis Tomlinson's mom, Johannah Deakin, passed away, but the 27-year-old singer is keeping her memory alive. On Thursday, Tomlinson dropped a new single titled "Two of Us," which is a beautiful tribute to his late mom that he said he "absolutely needed to write." "I just feel like musically, I almost needed to get this song off my chest," Tomlinson said in a statement. "People say writing is a part of therapy and in a way, I feel like I'd been avoiding writing this song because I knew I only had one chance to get it right. I don't mean to be too soppy about it, but if 'Two of Us' can help just one other person who's going through the tough time that I went through, then that would make me really happy." Tomlinson's mom may have passed away in December 2016 after a year-long battle with leukemia, but something tells us she would be very proud.
