Matt Lanter is 30 going on 17. The eternally youthful former 90210 star is back on The CW in its new series Star-Crossed, which just premiered this Monday. Matt stopped by our LA studios to talk about still being able to pull off playing a teenager as well as his new series' grown-up themes. He also shared a funny story about how the temporary tattoo he sports as his character Roman got in the way of some recent lunch plans. Catch Star-Crossed Monday nights at 8 p.m./7 p.m. CST.
