Are you Harry and Sandra or Jamie and Louise? Take our love quiz to find out!
IF you're fighting with your other half more often than you're hugging them, Harry Redknapp knows what's up.
The I'm A Celebrity winner claims he has never had a row lasting longer than ten minutes with wife of 54 years Sandra - and says the biggest issue among couples is incompatibility - even hinting it was the reason for footballer son Jamie's divorce from Strictly star Louise.
In an interview on Good Morning Britain this week, the football manager, 71, was asked by host Piers Morgan whether people "don't stick it out enough" when it comes to marriage.
Harry replied: "I don't know, it depends. People are not compatible, it's a problem. We've never had that."
Sarah Louise Ryan, relationship expert at , says the football manager and his other half - who met when they were both 17 years old and wed in 1967 - have scored well on the compatibility front.
"His wife Sandra is not only his life - partner but she truly is his best friend who he respects and adores above all else," she explains.
"This creates a strong foundation for the same outlook and wants in life - no matter what it throws at you."
Ryan explains that while their son Jamie and his ex-wife Louise - who were married in 1998 and officially called it a day last January - may have once been compatible, it is clear that this changed.
"Relationships are built on three pillars that create foundations for lasting love - trust, respect and communication," Ryan explains.
"At the very least couples need to ensure that they have matching values and a deep understanding of how each other communicates in a relationship."
