Christina Applegate

You grew up knowing Christina as Kelly Bundy, the slutty daughter of high-school football star Al "Did-he-ever-tell-you-he-threw-four-touchdowns-in-one-game?" Bundy on Married...With Children. She's graduated to larger roles, first as sexy anchor Veronica Corningstone in Anchorman, and more recently returning to TV with a starring role on ABC's Samantha Who? Watch her prove that lending only her voice to Alvin & the Chipmunks: The Squeakquel (in theaters now), makes it worth seeing.
