The 'Blurred Lines' singer - who announced on Monday (24.02.14) he and the actress were separating after eight years of marriage - is hoping to show his estranged spouse he can be a good husband in a bid to persuade her not to file for divorce.
A source told TMZ Robin ''desperately wants to save his marriage'' and is going to curb his partying ways as he wants to try and convince his childhood sweetheart he can change and be a good husband.
The source added that the singer is also ''really concerned'' about their three-year-old son, Julian, and doesn't want him raised in two separate homes.
The split comes after Robin was seen dancing closely to a mystery brunette in a nightclub in Paris in January, while last year another woman claimed the star had kissed her at a party in New York.
Robin and Paula, 38, announced on Monday they had ''mutually decided to separate at this time'', but will remain ''best friends''.
The singer had axed three consecutive concerts on his North American tour in the wake of the split, which are set to be rescheduled and the tour will resume in Washington tomorrow (27.02.14).
'House' star Laurie received star number 2,593 on the Hollywood Walk of Fame this week.
The word 'jealous' doesn't even cover it right now.
