People can't believe how old Mick Jagger is as he makes rare Oscars appearance

Viewers tuning into the 97th Academy Awards can't believe how old Mick Jagger is after he made a surprising Oscars appearance on Sunday (March 2).

The 97th Academy Awards held at the Dolby Theatre in Hollywood, Los Angeles, sees a ton of Oscars up for grabs tonight which include Best Picture, Best Actor, Best Director and Best Supporting Actor.

Comedian and former talk show host Conan O'Brien is hosting, and he has caused a bit of controversy with his opening skit.

Away from all of that, Jagger made a rare public appearance on stage, and many Oscars viewers can't quite believe the English musician is 81.

"Mick Jagger is still an apex rock star. That man is 81 years old," one person penned on Twitter.

A second added: "Mick Jagger is really 81 years old? He looks outstanding!" while a third remarked: "Mick Jagger looks pretty damn good for 81."

Jagger received a standing ovation after going up on the Oscars stage, showing the huge popularity the Englishman maintains in the US to this day.

"Mick Jagger Just Made My Night," another viewer penned on social media.

Meanwhile, a fellow fan added: "Standing ovation for Mick Jagger at the #Oscars simply for being Mick Jagger. I, too, stood up at home, audibly gasped in shock and applauded. A LEGENDDD."

At the pre-Oscars dinner party, the Rolling Stones frontman was joined by his girlfriend Melanie Hamrick, 37, at the Beverly Hills Hotel’s Polo Lounge in Los Angeles on Saturday (March 2).

Former professional ballerina Hamrick and ‘Satisfaction’ singer Jagger have been dating since 2014.

It’s well documented that the pair met backstage at a 2014 Rolling Stones show in Tokyo when the dancer was also touring Japan with the American Ballet Theatre.

Despite initially striking up a platonic relationship, the music industry veteran and Hamrick later began dating before welcoming their only son Deveraux ‘Devi’ Octavian Basil Jagger in 2016.

While Deveraux is the choreographer’s first child, he is the ‘Gimme Shelter’ hitmaker’s eighth.

The pair's age difference has often been a topic for discussion, with Hamrick previously talking about just that.

When asked about how it feels to be 44 years younger than Jagger, Hamrick told The Sunday Times: "I don’t think about it.

“Everyone’s going to have their opinion. If you think about others’ opinions, no matter where you are in life, you’re going to have a problem and you’re going to analyze it.”

“I put the blinders on. Am I happy? Yes. Are the people in my life happy? Yes. Am I hurting anyone? No. OK, they can mind their own business.”
