Kristen Bell and Dax Shepard have become some people's favorite couple in Hollywood, but others scrutinize their every move. Bell started dating Shepard in 2007. The couple got engaged in 2009, eventually tying the knot in 2013. Bell and Shepard went on to welcome daughters Lincoln (born in March 2013) and Delta (born in December 2014). While their relationship has made headlines since the start, Shepard's popular podcast, "Armchair Expert," and Bell's success on Netflix's Nobody Wants has put even more attention on the pair.
