Zeta Jones helps Gran enjoy knees-up

Catherine Zeta Jones has put the swagger back in her gran's step…with a new pair of knees.

The mega-rich star paid for the 86-year-old - also called Zeta - to have the operation done privately.

Catherine told US chatshow host Jay Leno that her grandma is now running around "like a little whippet".

She and husband Michael Douglas decided on the bizarre gift after Zeta revealed she needed knee replacements but could not face the operation.

Catherine, aged 34, told Leno: "She didn't want the whole anaesthetic thing."

But a doctor was found who could perform the surgery using an epidural injection, which numbs the spine.

Gran Zeta said at her home in Swansea: "Catherine's a very generous girl, always helping people."
