After Demi had her near-fatal overdose and then checked into rehab, Nick was one of the first people to publically express his love, support and care for Demi.
"Like all of you I am reeling at the news about Demi. All of us love her and need to pray for her to get well. She is a fighter. #prayfordemi."
But soon after, Nick got wrapped up in his love affair with now-wife Priyanka Chopra, planning the most outrageously amazing wedding of all time... which Demi was not invited to.
According to Us Magazine, Demi was so hurt by Nick not inviting her. "It broke her heart," a source told the mag.
Hopefully now that the wedding celebrations are over, and she is on her way to recovery, the pair can fix their friendship.
