Unfortunately "House of Carters" wasn't a big hit with the viewers, and after only eight episodes, it was not renewed for a second season.

The Backstreet Boys are currently in the middle of a residency at The Axis at Planet Hollywood in Las Vegas. Their time at The Axis is scheduled for March 1 - July 1. The residency is titled "Larger than Life," and all of the original band members, who have been together for 24 years, are taking part in it. There is no word yet whether or not Nick Carter will take any time off.

On April 24, Nick was a guest judge on "Dancing with the Stars." He was the first guest judge on season 24. In 2015, Nick was a contestant on "Dancing with the Stars" and was partnered with professional dancer Sharna Burgess. The pair finished in second place, losing to Bindi Irwin and her professional partner, Derek Hough.

More details on Bob Carter's death will be coming in the following days, as well as the funeral arrangements that the family is making.
