Emma Stone and Haim want to send you to the Spice Girls reunion tour

It’s not every day Oscar-winning actress Emma Stone and the sister-act pop trio Haim break out into song and dance to a Spice Girls jam.

The four friends announced on Wednesday, while singing and dancing in a video to the Spice Girls’ “Stop,” that donating to a handful of charities could land a winner and a friend in London for the Spice Girls’ partial reunion tour this summer.

In a video posted on Haim’s Instagram, Stone, accompanied by Este, Danielle and Alana Haim, dance and lip sync to the pop song, pausing between lines to publicize the Omaze campaign.

Donations to enter the contest will benefit charities dedicated to fostering gender equality, eradicating homelessness and helping those with mental health and learning disorders. The charities include PATH, Girl Up, Child Mind Institute, Comic Relief and the Los Angeles LGBT Center.

Victoria Beckham, also known as Posh Spice, will be absent from the Spice Girls’ upcoming tour. She told “Good Morning America” Thursday that her busy schedule kept her from joining.

Omaze is an online fundraising platform that raffles prizes in support of social causes.
