Taylor Swift is so happy she's "Never Ever Getting Back Together" with one of her exes that she threw a dance party.

In sneak preview of the breakup anthem's video, Swift looks like she's having a blast dancing exuberantly along with a group of friends -- including a dude in a donkey costume. The 22-year-old singer wears a vintage-inspired, daisy-printed dress and bright red lipstick, which only emphasizes her smile and how thrilled she is to have kicked her ex to the curb.

The full video, directed by Declan Whitebloom, will premiere at 7:49 p.m. ET on MTV, CMT and TeenNick on Aug. 30.

The song is the first single off of Swift's forthcoming album "Red" and has already broken records, as the best-selling digital single in a week by a woman with 636,000 paid downloads, reports MTV News.

Swift co-wrote the song with Swedish hit-makers Max Martin and Johan Shellback, and revealed to "Nightline" that song is completely autobiographical.

Swift explained that the inspiration for the song came after one of her ex-boyfriend's (who remains nameless) friends came into the studio and said he had heard they were getting back together -- which was not the case.

"When he leaves, Max and Johan are like, ‘So what’s the story behind that?’ And so I start telling them the story of break up, get back together, break up, get back together, just, ugh, the worst," she explained. C'est la vie, no?
