Is iCarly iGay?

For those of you who have the guilty pleasure of a tween sitcom as i do, maybe you can shed some light on this subject.  iCarly, starring Miranda Cosgrove as 14 year old Carly who lives in Seattle with her older brother has her own webshow entitled, you guessed it, "iCarly".  Carly hosts the show with best friend Sam, played by Jennette McCurdy.  Is it wrong to believe that Sam is gay?  The most recent episode, due to air Saturday night is entitled, "iMake Same Girlier" ...now how many friends have we had in the past that tried to make us more girly?  Is nichelodeon writing a tween lesbian character into the show?  what are your thoughts!!!
