Friends fear for 'exhausted' Posh

Victoria Beckham's friends fear she may be heading for a collapse due to her hectic schedule.

The Spice Girls ended their reunion tour last week and Posh immediately focused her energy back into her fashion projects.

A friend told Grazia: "Victoria has been running on empty for the last few months and is very, very tired.

"The tour has completely drained all the energy out of her, as it did the other girls, but on top of her Spice Girl commitments, Victoria has continued to invest masses of energy into her fashion career. Everyone is very worried she might keel over."

Beckham spent several days sitting through shows at last month's New York fashion week, before performing with the band in the evenings.

The source added: "Victoria kept saying how exhausted she was and there were moments backstage when she had to stop and sit down or lean against a wall because she felt so wobbly."
