NASCAR driver Greg Biffle was a proud dad away from the race track. While the American motorsports racing driver was known for winning nearly 19 races during the height of his career between 2003 and 2016, Biffle was also a devoted father to two children. Biffle became a dad in 2011 when his then-wife, Nicole Lunders, welcomed a baby girl named Emma. "Starting to see kids around or your friends having kids makes you think differently about it," Biffle told USA Today in June 2014.
