Los Angeles - Nick Carter and Lauren Kitt have welcomed their first child together.
The Backstreet Boys singer's wife had a water birth at their home on Tuesday where the couple welcomed son Odin Reign, according to Entertainment Tonight.
Nick, 36, and fitness expert and actress Lauren, 32 - who tied the knot in 2014 - announced last year that they were expecting a baby and Nick has praised his wife for being "super cool" during the pregnancy.
He previously said: "You know the thing with my wife is that she is super-cool. Things are not over the top and changing, it is all gradual and comfortable. You know people are saying to me that my life is going to change, trust me. When it comes to the life I have Lauren making the process really amazing and comfortable.
"It's cool to have some time to prepare. I've really been thinking about living in the moment and enjoying every day that I have with my wife. I'm enjoying the process, because I've heard that your life will change and your priorities will change and that's great. So we are enjoying the time we have right now."
However, Nick admitted that he was worried he would be anxious during the birth.
He said: "The delivery stage and all that, I will have anxiety - but overall I am having a good time."
