Michael Douglas' father has urged his son to patch things up with Catherine Zeta-Jones.

The Hollywood couple called time on their relationship earlier this week in order to "evaluate their marriage," but Michael's dad Kirk Jones has begged the Behind The Candelabra star to save his romance before it's too late. "Kirk likes Catherine and has told Michael to sort his problems out. He's been with his wife Anne for almost 60 years and thinks marriage is about sticking with someone through good and bad," a source close to the family told The Sun.

Neither Michael nor Catherine have made any movements to file for divorce or legally separate and are said to be working through their differences. "Michael is still talking to Catherine and their family and friends are trying to help them work through their issues," a friend of the couple said.

The pair's 13-year marriage has been rocked by numerous stresses in the last three years with Michael being diagnosed with throat cancer in 2010 - which he beat - and Catherine suffering from bouts of bipolar II disorder, most recently in May this year.

The Red 2 star is reportedly seeking guidance from a counselor as she wants to do everything in her power to make sure their marriage is back on track as soon as possible. "Catherine has already spoken with a marriage guidance expert who now wants to see them individually and together. She is painfully aware this could be the last throw of the dice," a source previously said.
