Emma Stone cries at Melanie Brown message

Actress Emma Stone was overcome with emotion during an interview in Australia when she received a personal message from former Spice Girls star Melanie Brown.

The Amazing Spider-Man star joined the hosts of Sydney's 2Day FM to talk about her new superhero sequel and fought back tears when she realised she came close to meeting her pop idol, who often hosts a show on the station.

Stone's voice trembled as presenters Merrick Watts and Sophie Monk apologised for the singer's absence before playing her a personalised message from Brown.

The actress said, "Wait, Mel B could have been here? I'm going to cry. Oh my God, is Mel B talking to me? I'm so excited, I'm legitimately crying. I'm the biggest Spice Girls fan ever."

In the video message, Brown challenged her superfan to sing a Spice Girls song, and Stone battled to keep her emotions under control to perform a rendition of the rap from the group's breakthrough track Wannabe.
