The Spice Girls are hoping to regroup for another comeback tour but the bandmembers are struggling to convince Victoria Beckham.
The 'Wannabe' hitmakers thrilled fans when they returned for a sold-out world trek in 2007 and 2008, the first time the original line-up had performed together since Geri Halliwell quit to go solo in 1998, Daily Mirror online reported.
Following the jaunt, Beckham vowed to hang up her microphone to concentrate on her fashion ventures.
The girl group is now reportedly eager to get back on stage - but singers Halliwell, Melanie Brown, Emma Bunton and Melanie Chisholm are struggling to persuade Beckham to join them.
"The girls are so excited. They are buzzing about getting back together and each have so many new ideas and so much to bring to the table. They are desperate to get Posh (Beckham) on board, but that is the sticking point," a source told the publication.
"Although she's still so nostalgic about the good old days, she has moved on now and is relishing the fashion world. They don't want to give up on her, but have so many plans," the source added.
"The way things are going they might have to go on without her if she doesn't come round soon," the source said.
