The Backstreet Boys singer, who's in the middle of his multi-city solo tour, honored his previously booked engagement at the iHeart Performance Studio in Bala Cynwyd, PA Sunday evening instead of heading to his sister's services taking place seven hours away.

This is Nick's third performance since Leslie passed away from a drug overdose on Feb. 1 at the age of 25.

On Monday, the 32-year-old addressed his absence from his sister's services, telling TMZ, "I wanted to be at my sister's funeral, but my family has always had a complicated dynamic. There are so many emotions for me surrounding the loss of my sister. I am trying to stay healthy, positive, and focused."

Sources close to TMZ say that Nick feels his family went out of their way to make sure that he was not included.

On the day of his sister's death, a statement was released on his website, nickcarter.net, which read: "Nick Carter is thankful to the many people and the fans who have shared their wishes and prayers during this tragic time. We want to let the fans know the tour will go on as promised," with Nick adding "Performing is cathartic to me and I am dedicating the rest of my tour to my sister since she loved to watch me perform."
