J.K. Rowling bribed fans with new 'Harry Potter' information to get them to cheer for her favorite rugby team

J.K Rowling is known for using Twitter to release new information about Harry Potter characters, but on Saturday, the author took things to the next level — she used the promise of revealing Sirius Black's birthday as a bribe to get her followers to cheer on the Scottish rugby team. 

It all started with a tweet from Rowling on Saturday.

The author was on her way to watch Scottish rugby team play in the Rugby World Cup in Newcastle, England. 

"If lots of you tweet #AsOne to support Scotland, you can have Sirius's birthday," the author tweeted. 

Off to Newcastle for #SAMvSCO and if lots of you tweet #AsOne to support Scotland, you can have Sirius's birthday! #RugbyWorldCup
