Cameron Diaz has ''persuaded'' Nicole Richie to give Joel Madden another chance.

The 'Sex Tape' star has reportedly been able to dissuade the 33-year-old television personality from filing for divorce from the musician.

A source said: ''Cam has persuaded Nicole to stop her divorce proceedings for now.

''Ever since Cam got married, Nicole's been turning to her for advice.''

The 42-year-old beauty - who is married to Joel's brother Benji Madden - is also getting support from her husband, who wants the pair to make each other their priority.

The source added to Life & Style magazine: ''Benji loves Nicole and Joel and thinks they can work it out.

''If they just spend more time together and stop making their careers a priority.''

Meanwhile, Nicole - who has seven-year-old daughter Harlow and five-year-old son Sparrow with Joel - previously revealed she first set Cameron and Benji up.

She shared: ''Yes. I'm going to take responsibility for everything! I approve of anything that's going to make Benji happy.

''I am a devoted sister-in-law. I'm happy for anyone who is happy, and I want everyone to be surrounded with love.''
