London: Michael Douglas and Catherine Zeta Jones` 13-year-of marriage may be in its last throes.
An insider has revealed that the `Basic Instinct` star is going to announce the split and Jones is trying to save the marriage, the Mirror reported.
According to another report, a multi-million dollar divorce row will be started by the `No Reservations` star.
The 68-year-old actor was spotted all by himself, while arriving in Sardinia by private jet, as his 43-year-old wife was nowhere to be seen.
The couple has not been pictured together in public for four months.
