Amanda Bynes and Jennie Garth reminded fans of all the reasons they love the actresses during their run on What I Like About You. The duo starred as sisters Holly and Val Tyler, respectively, on the WB sitcom from 2002 to 2006. For four seasons, they cracked up viewers alongside their costars Nick Zano (Vince), Leslie Grossman (Lauren), Wesley Jonathan (Gary) and Allison Munn (Tina). As often happens in the realm of television, Bynes and Zano began dating in 2003 as their characters did the same on screen.
