From TMZ
Megan filed legal docs to get the restraining order against her label, 1501 Certified Entertainment, and her distributor 300 Entertainment. According to the docs, obtained by TMZ Hip Hop, Megan claims 1501 made "threatening and retaliatory" moves to block Megan from using her own music in connection with the AMAs ... which will be handed out this coming Sunday.
She doesn't specify what 1501 and/or 300 Entertainment allegedly said or did to mess with the AMA broadcast on ABC -- but a judge heard enough to grant the temporary restraining order. Both companies are now blocked from interfering with her music being used on the award show.
