Alison Sweeney is busy juggling the roles of host for NBC's hit reality series "The Biggest Loser" and the award-winning Sami Brady on NBC's hit daytime drama "Days of our Lives."

Sweeney made her debut as host for Season 4 of "The Biggest Loser" on September 4, 2007 and is currently completing production on Season 7, which is airing Tuesdays on NBC (8-10 pm ET/PT). Having openly discussed her own weight loss struggles, Sweeney was thrilled when the show producers asked her to join the show. Since then, Sweeney has been featured in such magazines as People, US Weekly, OK!, Quick and Simple, Complete Woman, Health and many more. Her talk show appearances include "The Tonight Show with Jay Leno," "Ellen," "Today," "Rachael Ray" and several segments for "Access Hollywood."

At age 16, Sweeney joined the cast of "Days of our Lives" and in her 15+ years as Sami Brady, she has transitioned from a rebellious teenager to a devoted single mother with many detours along the way. Sami has tackled a variety of controversial storylines including bulimia, date rape, teen pregnancy, and capital punishment.

Sweeney's performance has garnered numerous awards including The Soap Opera Digest Awards four times (1986, '98, '99 and 2001) for the role of Favorite Villain and the award for Favorite Good Girl in 2001. Sweeney also won the award for America's Favorite Villain at the 29th Annual Daytime Emmy Awards. She can be seen on "Days of our Lives" weekdays on NBC.

Her additional television credits include "Las Vegas," "Friends" and "American Dreams." On the reality front, she competed in "Celebrity Fear Factor," "Celebrity Cooking Showdown" and "1 vs. 100."

Sweeney is also an accomplished author with the 2004 release of her book, "All The Days of My Life (So Far)." The book gives audiences a glimpse into Sweeney's personal life by describing her experience as a child actor, life on the set of "Days of our Lives," painful high school memories and the struggle to lose weight and keep it off.

Recently, Sweeney tackled the role of producer and director with the creation of "In Tune," an on-line soap opera set in a music store. She also is busy working with Huggies on their 30th anniversary initiatives and co-hosted the MDA Telethon again in September for the second consecutive year.

She currently resides in Los Angeles with her husband, a California Highway Patrol officer, and their three-year-old son Ben and newborn daughter Megan.
