Blake Lively's Brother: Eric Lively
Blake Lively of Gossip Girl has a 31-year-old brother named Eric, who, not surprisingly, has modeled for Abercrombie & Fitch, Levi's, and Tommy Hilfiger. He had a small role in American Pie in 1999 and was also on The L Word. Fun fact: Eric played Stephanie Tanner's boyfriend on Full House when he was 13! Blake also has two half-sisters, Lori and Robyn, and a half-brother, Jason.
