Harry Styles' hair is not the same "as it was."

The 29-year-old English singer was reportedly spotted with his girlfriend Taylor Russell and a group of friends at U2's concert at the Las Vegas Sphere with a new hairstyle - a buzzcut.

In the photos surfacing online, Harry, known for his long, luscious locks for a long time, had his new hairstyle on full display at the concert. With no cap or anything, in his plain white t-shirt, the "Love On Tour" artist was seen standing with his arm around his girlfriend. 

With this new update about Harry, some fans are referencing song lyrics from American singer-songwriter Taylor Swift, Harry's ex-girlfriend.

One fan tweeted a collage of Harry's long locks with a caption quoting a few lines from Swift's "Bigger Than The Whole Sky" that said, "Goodbye, goodbye. You were bigger than the whole sky." 

Several fans also linked it to "Now That We Don't Talk," the singer's recent track release from "1989." They claim that Swift's song is to blame for Harry's sudden buzzcut.

"Harry Styles shaved his hair so he could beat the 'Now That We Don't Talk' allegations," one fan tweeted. Another quipped, "Harry Styles heard 'Now That We Don't Talk' and decided shaving his head was the best option."

"Harry heard 'Now That We Don't Talk' and decided to take matters into his own hands," a different netizen commented.

"[This is] Harry Styles after hearing 'You grew your hair long, you got new icons' from 'Now That We Don't Talk.'" wrote another.

 

Taylor Swift released her version of "Now That We Don't Talk" from the vault on Oct. 27. Per Genius, the track "explores the feelings that arise as a once-important relationship fades away, painting a picture of change and distance between two people who used to be close."

While Swift didn't really reveal that the song was about her ex-boyfriend Harry Styles, some fans speculated that she might be talking about him, especially with the line, "You grew your hair long," which, according to fans, reflected Harry's previous hairstyle.

Taylor Swift and Harry Styles' story started when they met backstage at the 2012 Kids Choice Awards, per People. In November of the same year, romance rumors between the two began when Styles paid Swift a visit at the rehearsals of "The X Factor" ahead of her performance.

The next month, the two were spotted on a date in Central Park before spending time together at a birthday party, spending the holiday at Park City, Utah and the Caribbean and celebrating Swift's birthday in England.

When Swift performed on "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest" as the year ended, the two shared a kiss at midnight.

But in January 2013, the two reportedly broke up.
