Harry Styles, officially, joined the list of celebrities who have done transformation on their looks during the COVID-19 quarantine. The "Watermelon Sugar" singer debuted his new '70s-style mustache but fans were divided about it. Many adored the One Direction member's new look while others begged Styles to shave it off.

Styles is, currently, enjoying his time in Italy. Over the weekend, he visited Villa Manodori in Modena, Italy, and took some photos there. 

Chef Massimo Bottura of Villa Manodori shared on his Instagram Story a photo of him and Styles, saying the singer just made a stop at the Osteria Francescana restaurant as he traveled through. The company, also, shared another photo of the "Sign of the Times" singer on their official IG page. 

In the snap, Harry was seen sporting a mustache while holding a bottle of balsamic vinegar. He was clad in a pair of straight-legged jeans, a green and white striped t-shirt, and yellow-tinted sunglasses.

Directioners were quick to share their reactions to Styles' new look. Many were impressed by how the singer/actor nailed the '70s look. 

Another fan joked that Styles's mustache made him "my new Mario kart favorite player." Others compare Harry's new facial hair to Freddie Mercury and Billy Hargrove (Dacre Montgomery) of Stranger Things. 

Some fans, on the other hand, were calling for the immediate return of the freshly-shaven look of Harry. One tweeted a petition for the "Falling" singer to save his mustache. 

Harry Styles with a mustache doesn't come as a big surprise to many of his fans. In April, he was already spotted sporting a "quarantine beard." It seems like he decided to make it into a proper mustache.

Back in 2011, Styles also tweeted about wanting to have a mustache. He said he wants to have Super Mario-like facial hair. Judging from his new look, Harry definitely checked "having a mustache" off from his bucket-list. 

Meanwhile, Styles revealed, in an interview, with BBC Radio 1Xtra Residency in March that he was learning Italian and sign language while in quarantine. He added that this is a perfect time to learn a new skill or a hobby as many have a lot of spare time while staying at home. 

Many, also, praised Harry Styles for keeping himself safe by considering driving to Italy from the U.K. rather than flying. However, some also reminded the "Golden" singer to always wear a mask.
