Born November 9, 1973, in Harlan, Ky., Nick Lachey attended the Cincinnati School for Creative and Performing Arts, where he met his fellow 98 Degrees bandmates. As writer and lead vocalist, Lachey helped his band sell more than 10 million albums.
In October 2002, Lachey married Jessica Simpson. Their relationship was the centerpiece of the 2002-2005 show Newlyweds, which chronicled the young couple's wedded bliss.
Ironically, the two filed for divorce in December 2005. After the split, Lachey tried his hand at a solo music career. His album, What's Left of Me deals largely with his relationship with Simpson.
In March 2008, Lachey announced that he is re-teaming with MTV to produce an unscripted reality show version of Fame titled High School Musical: Get in the Picture.
Since 2006, Lachey has been dating TV personality Vanessa Minnillo. Though the couple briefly split in June 2009, they patched things up a few months later. The couple married in July 2011 and welcomed son Camden in September 2012.
