Mel B just threw fuel on her fight with Victoria Beckham and we're shook.

If you want to know how Mel B feels about her former Spice Girls bandmate Victoria Beckham, you really don’t need to ask.

Because she made it pretty damn obvious with her choice of Halloween costume this year.

The Scary Spice singer, whose real name is Melanie Brown, and her friend dressed up as Posh and Becks for Heidi Klum’s annual Halloween party.

Mel wore a mask of Victoria’s face and was accompanied by her friend, hairdresser Gary Madatyan, who wore an LA Galaxy football shirt to impersonate footballer David.

The America’s Got Talent judge also held a sign reading: “No I am not going on tour”, a reference to earlier reports that all of the original band members, excluding Victoria, would be going on tour this year.

For oh, about two years, Mel, along with Emma 'Baby' Bunton, Geri 'Ginger' Halliwell and sometimes Melanie 'Sporty' Chisholm have hinted at a Spice Girls reunion and tour.

The hold-up has always seemed to be that Posh has not been keen on the idea - with reports that the 44-year-old is concerned about leaving her family and fashion label for months to tour. (Fair enough).

When it looked like Baby, Ginger and Scary Spice would be forming a trio to tour as a new band (a rumour later quashed by Mel B) in 2016, Victoria told Sunday Times Magazine she was happy for her former bandmates.

"I do think they should sing new material, though, because what we did as the Spice Girls was so special. If they sang Spice Girls songs, I think I might be a bit sad," she told the newspaper.

Meanwhile, Mel C has previously said she wouldn't consider touring unless the full band was together.

But maybe she's come around - because the four women will be appearing on UK talk show The Jonathan Ross Show on Saturday, 10 November, where they are said to be making an announcement.

Naturally, fans are hoping this means they are finally going to confirm a tour they've been teasing for so long.

On Wednesday, Mel B joined other A-listers at model Heidi Klum's annual Halloween party in New York.

Klum, 45, is known for going all in with her outfit and this year was no different when she stepped out as the ogre version of Fiona from Shrek.

She posted videos to social media showing her having a prosthetic face and green paint applied. Her rumoured boyfriend, Tom Kaulitz, dressed as Shrek.
