Cameron Diaz hasn't been in a movie since 2014's "Annie."

The popular actress, 44, who was once one of Hollywood's highest-paid female stars making $15 million per film, recently opened up to pal Gwyneth Paltrow about why she retreated from the public eye.

"I just went, 'I can't really say who I am to myself,' which is a hard thing to face up to," she said at the Goop Wellness Summit over the weekend. "I felt the need to make myself whole."

The actress doesn't have any future projects listed on IMDB and hasn't been linked to any upcoming films.

Diaz was on a panel with Tory Burch, Miranda Kerr and sister-in-law Nicole Richie, who is married to Diaz's husband Benji Madden's brother, Joel. Paltrow moderated part of the event and asked Diaz "what was it that kept [her] from getting married until [she was] 40?"

"Forty-one!" Diaz playfully corrected her. "I think it's a matter of I just hadn't met my husband, you know? I had boyfriends before. And there's a really, really distinct different between husbands and boyfriends. And I have a husband who is just my partner in life and in everything."

Diaz and Madden started dating in the spring of 2014 and got married eight months later.

"Talk about two very different people," she continued. "We are so different from one another, but we share the same values -- we're totally two peas in a pod. We are both just weird enough for each other."

"We women are objectified so much," Diaz went on. "Somehow my husband has just been able to kind of show me what it's like not to have that be part of a relationship and being equal."

We hope to see Cameron Diaz back on screen soon, but we're also glad to see how happy she is with her husband, Benji Madden.
