Adam Brody is getting a tad old for the teen drama that made him famous, specifically 'The O.C.,' but it's okay, because we've found his replacement in 'Pretty Little Liars' actor Brendan Robinson -- who's practically his younger brother but with more expressive eyebrows.

Robinson is best known for his ambiguous role as Lucas on the ABC Family mystery/drama 'Pretty Little Liars,' where he was once a suspect in the murder of character Alison, a possible blackmailer who at one point may or may not have been dead. It's hard to keep track of these things.

Brody played Seth on an equally convoluted teen drama, 'The O.C.,' but has since gone onto bigger and better things. He recently starred in the indie-darling 'The Oranges' alongside real-life girlfriend Leighton Meester, and also appears in the apocalyptic comedy 'Seeking a Friend for the End of the World' and the biopic 'Lovelace' with Amanda Seyfried.
