American Music Award Nominations And 'Jackass 3D' Stunts In Today's Tweet Dreams

"Sesame Street" may have had no love for Katy Perry, but the American Music Awards sure did! The "Teenage Dream" singer was nominated for three awards today, along with a bevy of some of Crush's favorite artists like Taylor Swift and Justin Bieber (who wrote via tweet, "I heard about being nominated for 4 Ama's!!! I'm so excited! Thanks to all for supporting me!!!") Katy (pictured), who is up for Favorite Female Artist, Favorite Album and the coveted Artist of the Year, posted to fans, "Ohhh emmm geee! Thank you so much!" Fellow nominee Chris Brown took to his Twitter to ask for votes, "The nominations are in! Head over to to vote for me for Fave Male Artist in the Soul/R&B category!"

Speaking of promotion, Johnny Knoxville and the rest of the guys from "Jackass 3D" have been making the rounds talking about their latest installment of shenanigans (as Jeremy Piven put it, "Some people have to bungie jump in port-a-potties to make a living..."). Martha Stewart pondered, "we have funny sketches with johnny knoxville and pumpkins will he be ajackass??" while Jimmy Fallon alerted followers, "Johnny Knoxville on tonight doing a stunt. NBC is nervous. Can't wait for this movie."
