Harry Styles sends fans into a meltdown after debuting his new mullet haircut during his surprise performance with Stevie Nicks

Harry Styles sent fans into a frenzy after showing off his new haircut during his surprise appearance at Stevie Nicks’ BST Hyde Park concert.

The 30-year-old Watermelon Sugar singer joined the 76-year-old Fleetwood Mac icon in an emotional tribute to her late bandmate Christine McVie on her 81st birthday.

Christine tragically passed away in December 2022 after suffering a stroke during her battle with cancer.

And in his surprise appearance on Friday, Harry showed off his latest haircut, showing off his much shorter and curlier mullet, along with a new moustache.

Harry’s fans couldn’t contain their excitement over his latest style and took to X, formerly known as Twitter, to send their shocked reactions.

For the glittering event, Harry joined Stevie on stage for a performance of her classic hits Stop Draggin’ My Heart Around and Landslide, before paying tribute to her late girlfriend.

As Harry looked on, an emotional Stevie told the crowd: “I just want you to know that Christine was my girl and she loved us all and today was her birthday.”

‘You all helped me get through it [her death] and I want you to know how much I appreciate that’.

Before he said to Harry, ‘Harry, I thank you, we thank you!’.

Stevie previously revealed that Christine’s death was the final nail in the coffin of their legendary rock band Fleetwood Mac after five decades.

The classic lineup – featuring John McVie, Lindsey Buckingham and Mick Fleetwood – last performed together during their MusiCares tribute at Radio City Music Hall in Manhattan in 2018.

Shortly afterwards, Buckingham was fired and replaced by singer-guitarist Mike Campbell and musician Neil Finn, who joined Fleetwood Mac for their 88-date An Evening with Fleetwood Mac tour in 2018–2019.

“We had a really great time and it was a great tour. That was in the realm of possibility,” the 75-year-old rock queen said. Vulture.

“But when Christine died, I thought, you can’t replace her. You just can’t. Without her, what is it? You know what I mean? She was like my soul mate, my musical soul mate, and my best friend who I spent more time with than any other best friend outside of Fleetwood Mac.”

Stevie (born Stephanie) compared her relationship with the British keyboardist/singer to Taylor Swift’s 2022 song You’re on Your Own, Kid, in which she wrote the line “you always have been.”

“That was Christine and I. We were on our own in that band. We always were. We protected each other,” Nicks explained.

“Who am I going to look at on the right and not have them standing there behind that Hammond organ? When she died, I thought, we really can’t go on with this. There’s no reason for this.”

The Fleetwood Mc drummer said he still hopes Buckingham and lead singer Stevie can bury the hatchet.

The band co-founder stressed that a peaceful resolution between the two former bandmates and lovers does not necessarily mean Fleetwood Mac will come back to life.

β€œIt’s not a secret, it’s not a rumour that there’s an emotional wall,” the British musician, 77, said Mojo of the troubled relationship between Buckingham and Nicks, which dates back to the 1960s.

He added: ‘Stevie can clearly express how she feels and doesn’t feel, as can Lindsey. But I would personally like to see some healing between them – and that doesn’t necessarily have to take the form of a tour.’
