Justin Bieber + David Guetta Added to MTV EMA Awards Performance Lineup

The performance lineup for the MTV Europe Music Awards is starting to rival the lineup at September's VMAs, now that Justin Bieber and David Guetta have been added to the list.

Bieber and Guetta are both nominated for Best Male, while Bieber also appears in the Best Pop and Biggest Fans categories. Justin's girlfriend, Selena Gomez, is hosting the affair and has been given a performance slot of her own.

The big question for Bieber fans is what the teen star will choose to perform. Will he play a seasonal track from his new holiday album 'Under the Mistletoe,' or will he go for one of his biggest hits from the past year, like 'Never Say Never?' Will he premiere a new track, or better yet opt for a duet with Gomez?

Other acts already confirmed to play live on the show include Coldplay, Lady Gaga, Bruno Mars, LMFAO, Jessie J, Red Hot Chili Peppers and Snow Patrol. Gaga is the top contender with six nominations, including Best Song and Best Video.

Katy Perry will be in the house as a presenter, along with Snooki from 'Jersey Shore,' Amy Lee of Evanescence and David Hasselhoff. The EMAs take place in Belfast on Nov. 6.
