NASCAR driver Greg Biffle never officially retired, but he has spent the better part of the last decade with his family instead of on the track, getting behind the wheel only periodically - and with his wife, Cristina Biffle (née Grossu), usually in the stands. Since transitioning into semi-retirement, he has spent plenty of quality time with Cristina, whom he married in 2022. The two have made their share of public appearances together over the years, but it appears most of their time has been spent out of the spotlight, often on beach vacations and shared only via social media updates. Cristina is Greg's second wife. He was married to Nicole Lunders from 2007 until 2016, and they share one daughter, Elizabeth, born in 2011. He and Cristina have been together since shortly after his separation from Nicole, and they got engaged during a 2021 trip to the Bahamas. On Thursday, December 18, a plane belonging to Greg crashed while trying to land at an airport in North Carolina. A family friend reported that Greg, Cristina, their son Ryder and Emma were all on board. Who Was Greg Biffle?
