advert on my locked screen??

[vvv4n]

Hi there,

I'm new to the forums but I haven't been able to find an answer to my question as of yet. I have a Nokia Lumia 900. While my phone is locked I get this advertisement for "riot fest" beneath my clock. How the heck do I get rid of it, anyone know?


Thanks.

Maybe its a Facebook event. Windows Phone automatically syncs Facebook events/birthdays to your phone , but there's also an option to only show events you've responded to.
