Alison Sweeney announced Tuesday she is leaving NBC's "Days of Our Lives" daytime soap opera after 21 years. Sweeney, 37, originated the "Days" role of Samantha "Sami" Brady when she was a teen and has also been the host of NBC's "The Biggest Loser" reality competition since 2007. "I have never had more than a two-week vacation [since starting on 'Days'] in that whole time and, yeah, it's awesome," Sweeney said on "The Ellen DeGeneres Show." "I I love Sami, I love Salem, I love my job, I love daytime, I love the fans, I love everything about it," Sweeney said, adding she simply wants to spend more time with her family. "My daughter just turned 5 and my son is 9, and I just want to be with them and enjoy my last year."
