Britney Spears did not visit her mum after she was rushed to hospital with pneumonia.

The snub apparently stems from mum Lynne's criticism of Britney's partying ways.

A source told the Daily Mirror: "Britney feels betrayed."

The Toxic singer used to ring Lynne up to ten times a day but apparently resents her for telling her to go to rehab and last Sunday (May 13) refused to call her on Mother's Day (it falls on a different day in the US) or her birthday.

Added salt in the emotional wound came when Lynne teamed up with Brit's ex Kevin Federline to look after the pair's children.
