Who's pissed off Justin and Selena?

Update: "Kidd" is referring to Kidd Kraddick, a radio DJ who was apparently making fun of Selena's mum's pregnancy on his radio show this morning.

Both tweets have since been deleted.

Audio of the show can be heard here - skip to 5:10. Thanks[info]kknee13 for the link!
