Adrianne Palicki
Adrianne Palicki (b. May 6 1983, Toledo, Ohio) is an American actress who currently stars as "Tyra Collette" on the NBC television series Friday Night Lights.
She appeared in the Aquaman-based WB pilot Mercy Reef as an evil siren, but the pilot was not picked up for series by the CW network, a result of The WB and UPN network merger, which occurred while the pilot was being filmed.
Other television credits include Smallville as Kara in the season 3 finale ("Covenant"). Palicki also starred in Supernatural as "Jessica Moore", Sam Winchester's doomed girlfriend, killed by a demon, in its pilot episode. The character reappears in the Supernatural season 2 episode, "What is and What Never Should Be".
December 2007, topless pictures of Palicki surfaced creating controversy between the actress and Friday Night Lights producers. [1]
