Nick and Lauren welcomed their first child, a son they named Odin, on April 19, 2016 — and talk about seeing double, Odin looks just like his daddy! On his third birthday, Nick wrote on Instagram: "Daddy loves you more than anything in the world. Thank you for being in my life," then later shared a video of the little one singing "Happy Birthday" to himself. Looks like he's also got talent just like his dad!
