Jennifer Garner has been in the spotlight since she played a CIA agent on "Alias," starting in 2001. Since then, Garner has solidified her status as a serious a-lister, earning roles in "Valentine's Day," "13 Going On 30" and "Juno."
The actress has made a habit of dating, and even marrying her co-stars. She met her first husband, Scott Foley, on the set of "Felicity" in 1998, and began dating her "Alias" cast mate Michael Vartan after they divorced in 2004. Garner worked with her current husband Ben Affleck in 2001's "Pearl Harbor" and 2003's "Daredevil," and the two married in 2005. Affleck and Garner have had three children together: Violet, Seraphina and Samuel.
