Carly's best friend, Sam, is constantly in trouble-she spends A LOT of time in the principal's office. But Carly loves that Sam is unpredictable, crazy fun, and most of all, a good friend. As for Sam and Freddie, not so much. Those two are engaged in an ongoing feud which frustrates Carly at times but provides good material for the show. A true original and a true friend, Sam is essential to "iCarly" and Carly herself.
Sam is played by the bubbly Jennette McCurdy. You might recognize her from her guest roles on Victorious, Zoey 101, True Jackson, VP, and the original Bertha in, Fred: The Movie. She also starred as Dory Serenson in the Nick original movie, The Last Day of Summer.
