Madonna has invited Britney & her children to stay with her & her family in London during the Holidays to help Britney cope with her recent divorce.

Madge has always had a thing for Britney, and Brit has always looked up to The Material Girl. No word yet if Britney has has accepted the invite.
The latest rumor in the Spears/Federline divorce is that Britney is looking to remove 'Federline' from the babies names' once the divorce is finalized.
The name never really 'went' with anything anyway.
