Is Lara Spencer secretly vying for Robin Roberts job on GMA?

It looks like Robin Roberts needs to watch her back for up and coming new Good Morning America correspondent Lara Spencer. Spencer, the former co-host of the tabloid show "The Insider", recently joined Good Morning America and according to my sources is aiming for the head co-anchor job currently occupied by Roberts. I'm hearing Spencer has already sweet talked her way to more airtime and it is starting to show on air. Roberts really does not know who she is dealing with when it comes to Spencer and has even taken the young correspondent under her wing to make sure she is a success on the morning show. Oh Robin, can't you see you're being played, allegedly?
