Madonna can't seem to do anything right by her fans lately. Not only did she cancel her Australian tour dates to spend time with her kids -- but she will also not be performing with Britney Spears and Christina Aguilera at her upcoming MDNA tour shows in Los Angeles. According to JustJared.com, Britney and Christina were rumored to be joining Madge for a special performance to follow up their set at the 2003 MTV Video Music Awards.
A source for Britney said, "We have no current plans to do anything with Madonna in the near future. We love M and are big supporters but Brit is currently focused on X Factor."
