Robin Thicke's dad is giving him marriage advice.

'Growing Pains' actor Alan Thicke- himself twice divorced - is helping coach his 'Blurred Lines' singer son in how to win wife Paula Patton back following their separation last month after eight years of marriage.

A source said: ''Robin's convinced that his smooth-talking dad - despite his own chequered romantic history - could help him win back his wife.''

Alan is said to have a close bond with Paula, who has three-year-old son Julian with Robin, and has been trying to talk her around.

The source added: ''Paula adores Alan and he adores her. He admitted he made a mess of his own love life and caused pain for his family with divorces.

''But he told Paula he believes she and Robin have the strength to get through this and save their union.''

Alan was previously married to Robin's mother, Gloria Loring, in 1970 but they divorced when their son was nine. He the went on to marry Gina Tolleson and they had a son together, Carter, but they split in 1999, and the actor wants his eldest son to learn form his mistakes.

The source told National Enquirer magazine: ''It's ironic that Alan's playing marriage counsellor. But he doesn't want his son to make the same mistakes he made.''
