Just last week Katy Perry was crowned the Queen of Twitter, so it’s no wonder boyfriendJohn Mayer wants a piece of the action by hacking her account!

Last night Katy’s Twitter fans got a surprise “tweat” (Tweet + treat) when the following appeared in their newsfeeds: “John here. Katy can't write because she's getting over Stevie Nicks dedicating Landslide to us at the Fleetwood Mac concert. Unforgettable.”

Stevie and Katy have been friends for years, with Stevie even narrating a teaser trailer for Katy’s The One That Got Away music video a couple of years ago.

And apparently the Fleetwood Mac singer, who was performing in Las Vegas, paid tribute to the cute couple during the gig last night.

But while Katy was getting totes emosh over the song dedication, naughty boy John was getting busy on his lady’s phone.

He also tweeted on Katy’s account: “While I'm at it I have a couple things I'd like to get off my-oh, she's motioning for the phone back. Gotta go!! –JM.”

Maybe John should take the opportunity to update his own Twitter page – he hasn’t tweeted since 20th December!
