Katy Perry crossed the line when she showed favoritism for "American Idol" favorite Adam Lambert last week -- and unless you DVR'd the live show, you'll never see her pink Glambert cape again.
If you go on iTunes and purchase Katy's performance from last week's "Idol", the closeup of her silk Glambert billboard has been altered -- you can't even tell there's writing on the cape.
The rest of the video is exactly the same -- we put the two different versions side-by-side so you can see.
Fox and iTunes both declined to comment.
