This week's Famous Face From Orange County is Jeff Timmons. Although Jeff Timmons is not from Orange County, he does reside there.
According to Wikepedia:
Jeff Timmons was the founding member of 98 Degrees. While studying Psychology at Kent State, Timmons decided to move to Los Angeles to pursue a career in entertainment. Although he received several acting jobs (including a commercial for the U.S. Navy), his passion belonged to music and he formed a singing group. The group formed independently and were later signed to the Motown label in the mid-1990s. After building popularity with their appearance in the movie Mulan, singing "True to Your Heart," a duet with labelmate Stevie Wonder, their success broke out in late 1998 with their album 98 Degrees and Rising, which included the hit singles "The Hardest Thing", "I Do (Cherish You)" and "Because of You". After the first album, 98 Degrees left Motown for its parent company, Universal Records. All four albums released by the group went platinum. The group toured internationally through 2002.
Jeff Timmons and his fellow 98 Degrees members came together to sing on Nick and Jessica's Christmas Special (2004).
