Mel B appeared to throw a whole lot of shade at Victoria Beckham by dressing up as her fellow Spice Girl for Heidi Klum's Halloween party.
Scary Spice wore a face mask of Victoria, which she paired with a signature Posh Spice shift dress.
Although that doesn't sound too petty, the cherry on top of the cake was Mel's choice of accessory.
The 43-year-old carried a sign with the message: "No I am not going on tour."
The sign could be a reference to Victoria's notorious decision to not join the other girls for the elusive reunion tour.
Just to rub it in a bit more, Mel's close friend Gary Madatyan dressed as David Beckham with a football shirt and sign, which said: "Please please please do it for the Spice fans".
In February, the five girls posted a selfie together which fuelled rumours that the 90s girl band would be getting back together.
It was the first time the group had been in the same room together in six years, but fan's dreams were squashed when no comeback news followed.
However, after the selfie surfaced, Victoria famously told Vogue: "I'm not going on tour. The girls aren't going on tour.
"It was so great to see the girls. We had such a fun lunch. It was really, really, really lovely. I still speak to them all individually, but for us all to get together was really lovely.
"There's something so strong in the message of what the Spice Girls stood for. What is that in the future? What does that look like? We were just bouncing ideas around. Brainstorming."
Mel's choice of costume comes just hours after Twitter lost its mind when it was revealed that the Spice Girls would be appearing on The Jonathan Ross Show next week, without Victoria.
The line up was accidentally leaked on the show's official website, but it was quickly taken down once the word spread.
A Spice Girls fan page also shared the exciting news with a picture of Mel B, Mel C, Geri, and Emma captioned: "Who's ready for a #SpiceGirlsReunion?"
