Nick Carter will resume his scheduled tour with the Backstreet Boys after the sudden death of younger sister Leslie, while brother Aaron is taking time off.

Carter, 32, is set to kick off the group's Europe-Asia tour in the spring and though fans speculated that he may drop out of the tour to mourn Leslie's loss, the singer explained his choice to instead dedicate the tour to Leslie.

"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," Carter's publicist Jack Ketsoyan, told E! News.

"Performing is cathartic to me and I am dedicating the rest of my tour to my sister since she loved to watch me perform," Nick said.

Younger brother Aaron, 24, is currently starring in the off-Broadway play "The Fantasticks," and confirmed that he will be taking time off from performing to grieve the loss of Leslie.

"Aaron is taking a few days off from the show," John Capo, the spokesperson for the production told E! News.

"His Fantasticks family loves him and offers him support and prayers during this difficult time," Capo continued.

"Aaron's understudy and friend, Matt Leisy, will be covering Aaron's role until his return. We thank everyone for the outpouring of concern for Aaron," he added.

On Tuesday The Christian Post broke the news of 25-year-old Leslie's tragic death, which remains unexplained.

"Our family is grieving right now and it's a private matter. We are deeply saddened for the loss of our beloved sister, daughter, and granddaughter, Leslie Carter," the Carter family said in a statement to Access Hollywood.

Leslie's cause of death is still being determined, and it will likely be weeks before an autopsy can confirm what led to the tragedy.

The mother of one is renowned for being the aspiring singer and sister of Aaron and Nick Carter on the family's E! reality show "House of Carters."
