Couples can survive extra-marital affairs but it is "extremely challenging", a psychologist has warned.
It comes after Foo Fighters singer Dave Grohl admitted becoming the father to a baby born "outside of my marriage".
The former Nirvana drummer (55) said he plans to be a "loving and supportive parent" to his new daughter in an Instagram post on Tuesday.
Dave Grohl, who shares three daughters with his wife of more than 20 years Jordyn Blum, said he loves his family and is doing "everything I can to regain their trust and earn their forgiveness".

Consultant clinical psychologist Dr Tara Logan Buckley told Lunchtime Live recovery from infidelity is possible.
"It's something we would hear day in and day out and there's various reasons why people cheat," she said.
"They can be complex and personal to everybody so everyone is unique in the reasons as to why and each relationship is unique into maybe what is missing or [a] lack of communication.
"Couples can recover from infidelity but it requires a lot of work, there's a lot of commitment and emotional healing on both parties.
"Recovery is possible but it's extremely challenging".
'Open communication'
Dr Buckley said there are several pillars to recovery and forgiveness.
"The very first thing is there has to be open communication, they have to be able to talk honestly with each other about what happened... and the issues that led to that infidelity," she said.
"The second part - and this is where a lot of couples actually struggle - is a lot of people go into victim blaming.
"The person who has cheated has to have remorse and accountability, that's one of the main things.
"Without genuine remorse and accountability for the actions none of that trust can be built".

"[Does] the other person have the ability to accept, forgive and to heal?
"Not a lot of people do and that's perfectly OK - they never got with their partner expecting them to cause this much pain to them," she said.
"If we look at the highest rates of divorce it is really in relationships where infidelity has been one of the leading factors to a marriage breakdown".
Dr Buckley added that older men can get involved in affairs "to prove that they still have it".
