BackStreet Boy Nick Cannon not invited to.

Nick Carter tells TMZ … he WANTED to attend his sister’s funeral in NY this weekend, but his own family made it impossible for him to be there.
25-year-old Leslie Carter was laid to rest at a small ceremony in Upstate New York this weekend after a suspected prescription drug overdose. Several family members were present at the funeral, including Aaron Carter, but Nick was not.
Nick — who was on the road performing at a concert at the time of the ceremony — tells TMZ, “I wanted to be at my sister’s funeral, but my family has always had a complicated dynamic.”
Nick would not get specific about the circumstances … but sources close to the singer tell TMZ … he feels family members went out of their way to make sure he was not included.
Nick adds, “There are so many emotions for me surrounding the loss of my sister. I am trying to stay healthy, positive, and focused.”
