Emma Stone cried after receiving a video message from Mel B.

The 25-year-old actress was devastated to learn she missed out on the chance to meet the former Spice Girls star during a radio interview in Australia, but her tears turned to happiness when she received a special clip to make up for her disappointment.

When 2Day FM's Merrick Watts and Sophie Monk told Emma their occasional co-host couldn't be there for the interview, the actress' eyes filled with tears and her voice cracked as she said: ''Wait, Mel B, could have been here? I'm gonna cry.''

The 'Amazing Spider-Man 2' star was then stunned as a video of Mel appeared, with her saying 'Hi Emma'.

The actress sobbed and exclaimed: ''Oh my god, is Mel B talking to me? Oh my god, I'm so excited. I'm legitimately crying. I'm the biggest Spice Girls fan ever.''

Referring to an interview Emma did in 2012 when she singled out Emma Bunton as her favourite Spice Girl, Mel added: ''First of all, I want to say I absolutely adore you. I love you. And I want to say thank you for being such a Spice Girl fan. But my question to you is, why did you like Baby Spice and not me more?

''Your punishment for that, is I want you to do a rendition of one of the Spice Girls songs.''

Emma then said: ''You guys, I'm really excited about this. I'm legitimately excited.''

She then chose 'Wannabe', and after initially stumbling over the lyrics, the actress - who is in a relationship with her 'Amazing Spider-Man 2' co-star Andrew Garfield - performed the first verse of the track before stopping to say: ''I'm crying...I love Mel B.''
