David and Victoria Beckham
In 2004, Miss Rebecca Loos shocked the world when she claimed she had been having an affair with football star David Beckham who was then with Real Madrid and was England's captain.
She was his personal assistant.
After the Loos revelations, another woman, Miss Sarah Marbeck, also claimed she had an affair with him.
Beckham has always denied the affairs and his wife and mother of his four children, ex-Spice Girl and now fashion designer, Victoria Beckham, has always stood by her husband.
Bill and Hillary Clinton
It's been almost two decades since the current US Secretary of State stood by her man when news emerged of an affair between the then-Democratic presidential candidate and Miss Gennifer Flowers, a nightclub singer who told a tabloid in a paid interview that they had had a 12-year relationship.
Mrs Hillary Clinton's proactive loyalty in 1992 was credited with rescuing her husband's presidential campaign after he admitted "causing pain" in his marriage.
She also stood by him in 1998 when his affair with a White House intern, Monica Lewinsky, led to impeachment proceedings. He was acquitted on all charges of perjury and obstruction of justice.
Eliot Spitzer and Silda Wall
As a tough-talking New York governor, Mr Spitzer had pledged to crack down on corruption and had built a reputation as a no-nonsense family man.
He allowed the use of phone taps in investigations which, ironically, led to his downfall, as financial irregularities in his accounts were red-flagged. They also taped him arranging for a high-priced prostitute.
He appeared at a press conference with his long-suffering wife, Ms Silda Wall, a corporate lawyer by training, standing glumly behind him.
She apparently blamed herself for his transgressions, because she felt that the wife was "supposed to take care of the sex", and reportedly told author Peter Elkind that it was "her failing" that she was not "adequate".
They remain married today, even though his political career imploded.
Dominique Strauss Kahn and Anne Sinclair
Once tipped to become the next French president, Mr Strauss-Kahn has seen his career crash since his arrest last May over the alleged rape of a New York hotel maid.
Charges were eventually dropped, but then Tristane Banon, a 32-year-old writer, accused Strauss-Kahn of trying to rape her in Paris in 2002. Although French magistrates found clear evidence of a "sexual assault", they took no action because the alleged crime was beyond the statute of limitations.
Now Mr Strauss-Kahn is at the centre of an investigation into an international vice ring, with numerous prostitutes alleging that they slept with him at orgies. He has admitted having a liberal sex life, but denies knowing that the women were call girls.
Ms Sinclair has provided moral and financial support throughout the sagas, paying her husband's legal fees from the fortune built by her grandfather, art dealer Paul Rosenberg.
John and Elizabeth Edwards
In 2008, Mr John Edwards, then a US Democratic Party presidential candidate, admitted to an affair.
His wife - who was suffering from cancer - released a statement supporting him. She said that her husband had made a "terrible mistake", but went on to praise him for "courage in the face of shame".
She also stood by her husband when he denied paternity of a daughter with his mistress.
However, it was later clear that the affair had been going on even when she issued that statement and Mr Edwards did father the child.
They separated and Mrs Edwards died from cancer in 2010.
