Victoria Beckham has told Geri Horner she won't be part of the Spice Girls reunion next year but has given the band her blessing to go ahead without her.

The 41-year-old designer had a ''secret'' meeting with her former bandmate to inform her she won't be joining her, Emma Bunton, Mel C and Mel B in 2016 to mark 20 years since their debut single 'Wannabe' and first album 'Spice'.

A source said: ''Victoria met Geri recently to have an afternoon together reminiscing about old times.

''Geri filled Victoria in on the plans for the reunion next year and while Victoria made it clear she couldn't make it, she said she was more than happy for the other girls to go ahead. It's wrong to suggest she would try to stop them doing it if the other girls wanted to.''

However, the brunette beauty - who was known as Posh Spice when in the band - may not be able to commit to the reunion due to her busy schedule but is adamant she'll support her former bandmates every step of the way.

The insider explained to The Sun newspaper: ''Victoria also told Geri she would be at one of the shows, or maybe more, cheering from the front row.''

Meanwhile, Geri - who was known by her nickname Ginger - confirmed last week the Spice Girls have had ''talks'' about honouring the landmark date but insisted she would have to remain tight-lipped on the finer details - for now.

She said: ''It almost feels you know that it (the Spice Girls) belongs to everyone, like a generation. So I think it's [a reunion is] one of those things that's been discussed, but until it's concrete I wouldn't announce it.''

The Spice Girls - which sold more than 85 million records - last performed together at the 2012 London Olympics.
