On Friday, Taylor Swift expressed her admiration for Delta Sigma Phi Fraternity's music video of her hit song "Shake it Off," People reports.

"I'm personally inviting all of these guys (and a date!) to a show on tour next year, it's on me. Nailed it, bros!," she tweeted about the fraternity brothers on Friday.

The Beta Mu chapter of Delta Sigma Phi first posted their "Shake it Off" lip sync YouTube video on Saturday, Sept. 6 and the video has already garnered over 2 million views and counting. The video features the frat boys lip syncing to Swift's latest hit while dancing down the halls of what appears to be their college dorm rooms. Check out the video below. 

Upon hearing the news that Taylor Swift herself endorsed the frat's video, some of the frat brothers took to Twitter to express their excitement. "This is quite simply the best day of my life. ‪#wemadeit," @The_DanTheMan tweeted.

Another frat brother, @MichaelSoder21, tweeted, "So...now all I need is a date to ‪@taylorswift13's concert."

Despite the praise and support that Swift's latest song has garnered from her fans, "Shake it Off" has still stirred up some major controversy and backlash.

Last month, Odd Future rapper Earl Sweatshirt slammed Swift for her "Shake it Off" music video, which incorporates backup dancers gyrating and twerking to her song.

"Haven't watched the taylor swift video and I don't need to watch it to tell you that it's inherently offensive and ultimately harmful," he tweeted.

He continued, "perpetuating black stereotypes to the same demographic of white girls who hide their prejudice by proclaiming their love of the culture for instance, those of you who are afraid of black people but love that in 2014 it's ok for you to be trill or twerk or say n-gga."

Taylor Swift did not respond to Earl's tweets and "Shake it Off" is currently No. 1 on iTunes.
