Lady Gaga, Katy Perry Score MTV Europe Music Awards Nominations

Gaga and Perry tie with five nominations each; Eminem close behind them with four nominations.

It'll be somewhat of a girls' night out at this year's MTV Europe Music Awards in November, with Lady Gaga and Katy Perry tied at five nominations each.

The ladies will go head-to-head in four categories: Best Pop Act, Best Song, Best Female Act and Best Video. Gaga is also up for Best Live Act, while Perry, who hosted the show last year, is up for Best World Stage performance for her fifth nomination.

Eminem follows right behind the ladies with four nominations: Best Song, Best Male Act, Best Hip Hop and Best Video for his Rihanna collaboration "Love the Way You Lie."

But it wouldn't be an awards show without Justin Bieber. Bieber, who won the Best New Artist Moonman at the VMAs last week, will compete against Ke$ha, B.o.B, Jason Derülo and Plan B as a Best New Act nominee at the EMAs.

Best Rock nominees include Kings of Leon, Linkin Park, 30 Seconds to Mars, Muse and Ozzy Osbourne. Lady Gaga and Katy Perry will compete against Usher, Miley Cyrus and Rihanna in the Best Pop category.

Justin Bieber is also up for Best Male, along with Eminem, Usher, Enrique Iglesias and awards show rabble-rouser Kanye West. Gaga and Katy Perry once again face off against Miley Cyrus and Rihanna in the Best Female category, this time joined by Shakira.

Best Alternative nominees include Gorillaz, Gossip, Paramore, Vampire Weekend and Arcade Fire. Best Hip Hop nominees are T.I., Eminem, Kanye West, Lil Wayne and Snoop Dogg.

Usher's "OMG" will try to fend off Katy Perry's "California Gurls," Eminem and Rihanna's "Love the Way You Lie," Rihanna's "Rude Boy" and Lady Gaga's "Bad Romance" for Best Song. 30 Seconds to Mars' "Kings and Queens," Katy Perry's "California Gurls," Lady Gaga and Beyoncé's "Telephone," Plan B's "Prayin'," and Eminem and Rihanna's "Love the Way You Lie" are all competing for Best Video.

Perry and Linkin Park will perform at this year's show. The host has not yet been announced.

The MTV Europe Music Awards will take place on November 7 in Madrid.
