Actress Cameron Diaz reportedly sought marriage advice from her close friend Drew Barrymore when she went through a rough patch with husband Benji Madden.

Diaz got married in January.

"Drew said Cam should let Benji know he's the most important man in her life and keep his ego padded. She's taking Drew's advice seriously. She wants to stay happily married," a source told OK! magazine, reports femalefirst.co.uk.

It appears that Diaz is sharing her newfound marriage tips with her brother-in-law Joel Madden, who is believed to be having trouble with wife Nicole Richie.

An insider said previously: "Joel is determined to fight for Nicole. He's been leaning on Cameron, saying he doesn't want to give up on the marriage. He says he'll do whatever he can to prove his devotion to her and their family."
