First there was 'Applause' and now there's...'Swine'?

Lady Gaga let her fans hear a preview of another song off her upcoming album 'ARTPOP,' when she tweeted lyrics and a clip of her iTunes Festival rehearsal. The song will presumably called 'Swine' and sounds quite different from her previous 'ARTPOP' single 'Applause.'

"I know you want me. You're just a pig in a human's body," she sings in the clip. "Squealer, squealer, squeal out! You're so disgusting. You're just a pig inside. Swine." She also plays the drums and the keyboard in the clip.

She also tweeted the lyric: "Maybe I should have a little more just to stay out of my mind? Cause its when I'm thinkin' with you that I act like a Swine! #Sept1"

Gaga will perform the song live on Sept. 1, at the iTunes Festival in London. You can watch the live performance at 4 p.m. EST on iTunes. Little monsters who are going to see the performance live won't have to worry about what to wear, as the 27-year-old pop star tweeted a list of outfits she wants to see.

"I will be providing a list of acceptable attire for #SwineFest throughout the week," she tweeted. "Item 1: Seashells. Item 2: Seahorses. 3: Starfish." She tweeted further options, which include a "bedazzled pig nose," "paint colored dreadlocks," "Bowie magician garb," and "#ARTCLOTHES," which are clothes that will get covered in live art.

Gaga recently performed 'Applause' live at the 2013 VMAs, in which she had multiple costume changes that showed the evolution of her career. Earlier this month she released the song a week early after it leaked, and she released the video soon after. Gaga also made headlines at the VMAs when she defended One Direction after the British boy band was booed while accepting the award for Best Summer Song.

'ARTPOP,' Gaga's fourth album, will be released Nov. 11. You can see the iTunes Festival rehearsal clip below.
