Teens take note!

Taylor Swift and Selena Gomez are among the stars set to battle it out for this year's Teen Choice Award trophies. Handed out during a live telecast Sunday on Fox, the TCA trophies will just be part of the night's annual festivities.

Gomez, Jason Derulo and One Republic are among the acts taking the stage for musical performances. And what would a teen awards fest be without an appearance from everyone's favorite film vampires? Taylor Lautner, Ashley Green, Nikki Reed and Robert Pattinson will be among the Twilight cast members in attendance.

Also this week, Sharks take over Discovery for the channel's annual Shark Week programming. On tap this time around: Saturday Night Live's Andy Samberg caps his time as host with a heart-pounding adventure all his own. He visits a reef in the Bahamas where different species commingle – and jumps in!

Lastly, be sure to pick up Grayson Chance's debut album, Hold on 'Til the Night. The 13-year-old YouTube phenom — whose 2010 cover of Lady Gaga's "Paparazzi" got more than 41 million hits — outdoes himself with 10 originals. Us Weekly's music critic Ian Drew suggests fans pay special attention to his tracks "Heart Like Stone" and "Unfriend You,"which feature Chance's gripping falsetto and seasoned vocal style.
