Nick Carter of the famous Backstreet Boys is to be a father soon. The singer, who is currently competing in the 21st edition of "Dancing with the Stars", and his wife Lauren Kitt Carter are expecting their first child.

Lauren, a fitness professional, whom Carter married in April 2014, is about four months pregnant.

"They are so happy and overjoyed," an insider said of the parents-to-be.

"They have been trying and waiting for such a long time," usmagazine.com quoted a source as saying.

The 35-year-old singer said in September 2014 that he knew Lauren was "the one" from the first minute they met.
