Viewers were left confused when Robbie Williams appeared as a hologram for his Soccer Aid performance.
The bizarre show ended with the 46-year-old singing with The Struts for a rendition of their new single 'Strange Days' at the end of the match.
Fans were left bemused when Robbie showed up - well, kind of - in a white jacket. He'd been superimposed onto the set with the help of a green screen, and performed harmonies while the band played live.
Lead singer Luke Spiller even 'put his arm around' Robbie's hologram at one stage. All very strange.

The weirdness of the whole thing wasn't lost on viewers.
One person wrote: "I'm at a loss for words on how f***ing weird this poorly imposed Robbie Williams gig is.
"Lad's probably just rocking out in his kitchen acting like he's headlining the O2. Strange."
Another commented: "I didn't think Soccer Aid could get any weirder yet here I am watching a photo-shopped Robbie Williams having a little sing along."

A third tweeted: "What the f*** is this beamed in holographic Robbie Williams weirdness? Who the f*** are The Struts? What's going on?"
This viewer had a visual representation of what Robbie's appearance looked like:
Another was equally confused:
Soccer Aid 2020 took place on 6 September in aid of UNICEF.

The annual charity event this year saw Love Island and I'm a Celeb stars taking each other on at Old Trafford.
Rest of the World XI won for the second consecutive year, after beating England on penalties.
Celebrities and former footballers made their debut, including Love Island's Iain Stirling and comedian Mo Gilligan. Ex-pros Kelly Smith MBE, David James and Patrice Evra also made appearances.
Some of the faces that returned to the event include Love Island-er Wes Brown, singer Olly Murs, personal training tycoon Joe Wicks, comedian Lee Mack and reality TV star Kem Cetinay.
At one point, Patrice Evra made a joke out of comedian Lee Mack with his skills for the Rest of the World - the Frenchman was back at Old Trafford, the stadium where he achieved a lot of success with Manchester United, for the charity match at the weekend.

Playing in an unfamiliar position, on the right side of the pitch, Evra squared up to Mack and then bamboozled him with a piece of skill, before playing the ball through the comedian's legs.
