Nick Carter Speaks Out

Saturday night brought him to Harrah's Resort in Atlantic City, where he hosted a party at The Pool After Dark following his Philly performance -- a concert that forced him to miss Leslie's funeral.

"I wanted to be at my sister's funeral, but my family has always had a complicated dynamic," Nick tells Insider.com. " I love my family. I want to thank everyone for all of their compassion and support that I have received during this most difficult time. There are so many emotions for me surrounding the loss of my sister. I am trying to stay healthy, positive and focused."

Sources add that Nick, who only drank water, was in a good mood and dedicated every song to Leslie's memory.
