Ozzy Osbourne shared a cheeky message with fans on Saturday night after performing live for the very last time.

The 76-year-old rocker joined his Black Sabbath bandmates on stage in his home city of Birmingham for the first time in 20 years as part of the Back to the Beginning farewell concert.

Fans travelled across the world to see Ozzy alongside Bill Ward, Tony Iommi and Geezer Butler one last time, but some were saddened by Ozzy's appearance, as he sat upon a throne to belt out some of their hit tracks.

Dressed in black with matching eye makeup, Ozzy - who previously revealed that he can no longer walk due to the progression of his Parkinson's disease - performed the songs I Don't Know, Mr. Crowley, Suicide Solution, Mama I'm Coming Home, and Crazy Train.

Once his performance was done, and he was wheeled off stage as fireworks went off, the father-of-six reportedly looked emotional as he said "thank you," and blew kisses and held his hands up high.

As he exited the stage, an expletive final message appeared on the large screens at football stadium at Villa Park, which read, "Thank you for everything, you guys are f***ing amazing. Birmingham Forever."

Other artists who performed on the night included Smashing Pumpkins frontman Billy Corgan, Limp Bizkit's Fred Durst, and Duff McKagan & Slash of Guns 'n Roses.

In an interview with Rolling Stone UK ahead of the concert, Ozzy's wife Sharon Osbourne admitted the show had been in the work for two years, and said she was feeling "so emotional" and described the day as "magic".

"It was just amazing how everybody said, 'yes, we wanna do it, we're there, we wanna support Sabbath and Ozzy and be there for the charity'. And so it's just been a pleasure dealing with everyone, and they've just been so generous with their time.

"Every single artist has just been fantastic," the former X Factor UK judge said, before she shared a message on behalf of her husband.

"Ozzy has finally got a chance to thank people for all their years of support and encouragement to him and really giving us the life that we have together. We appreciate everything that these fans have given us around the world," Sharon said.

Fans were ecstatic when news of the farewell concert was announced back in February. In an Instagram post Ozzy shared earlier this year, the music director of the show, Tom Morello said, "This will be the greatest heavy metal show ever." Tom is known as the guitarist for Rage Against The Machine.

A quote from Ozzy was shared in the post and read, "It’s my time to go Back to the Beginning….time for me to give back to the place where I was born. How blessed am I to do it with the help of people whom I love. Birmingham is the true home of metal. Birmingham Forever."
