Victoria Beckham won't be "pushed" into a Spice Girls reunion, says a source.
Mel B recently let slip that the group wants to perform at Britain's Queen Elizabeth's Diamond Jubilee celebrations later this year.
Sources close to Beckham claim that although the mother-of-four would consider a reunion she wants the agreement to be on her terms also.
"They never ruled out doing something again and Victoria is enthusiastic about a one-off performance. She's really busy, but she would find the time to do it. However, she won't be pushed into anything,'' an insider told UK magazine Closer.
Mel B made the blunder when she appeared on Australian television and was asked whether the girl band will perform at the 2012 London Olympic Games.
"Ooh, I think the Queen's Jubilee concert is the event I'd be looking at more closely for that to happen,'' she told breakfast show Sunrise.
Mel B's comments have caused quite a stir amongst Spice Girls fans. Beckham is said to be annoyed that her former bandmate let the plans slip, as she now feels obliged to commit.
"Mel B talking publicly about the reunion annoyed Victoria. It was supposed to be top secret until they all agreed,'' the source continued.
"Victoria is a bit wary of signing up, especially as Mel's husband, Stephen Belafonte, seems to be trying to muscle in, He's said he'd be happy to get involved since he manages Mel's career,' which raised a few eyebrows.
"Since Mel's been a judge on The X Factor in Australia, she seems to feel she's as big a star as Victoria is. In the past, they've rubbed each other up the wrong way and are clearly vying for the lead role again."
Beckham has good relationships with Emma Bunton and Mel C. However, she is not as close to Geri Halliwell and Mel B and is allegedly concerned about the friction this may cause.
"Victoria, Emma and Mel C never clashed that much and she'd love to make them happy by agreeing,'' an insider revealed.
"But Geri and Mel B still seem to have a competitive attitude, so Victoria is worried about clashing with them."
