Cameron Diaz has a lot on her mind lately.

For starters, the 41-year-old kicked off 2014 by offering advice on DEEPLY personal grooming, preaching against laser hair removal on the “lady bits.”

Soon after that, Diaz went on “Dr. Oz” to talk about how she stays … regular. Because, you know, everyone wants to know how the famous blonde “wakes up” her digestive tract in the mornings.

Moving on.

Now, the new author of "The Body Book" is talking about love, or the major downside of it. And considering she’s dated some big stars, like Justin Timberlake and Jared Leto, this is one topic Diaz can dish while we happily listen. But her take on romance is seriously a downer.

The New York Daily News is reporting that Diaz recently chatted with UK’s OK! Magazine, where she claimed that everyone has to endure some form of infidelity.

“Everybody has been cheated on, everyone will be cheated on,” said Diaz to the publication. “I can’t fix that, I don’t know how, I don’t have any judgment on anybody, I don’t know how to fix the problem.”

And no, this isn’t some marketing ploy to promote her newest film, “The Other Woman,” in which her character discovers her boyfriend is married and has another girlfriend on the side.

“My statement is that I am actually not interested in making movies about men cheating on women; it’s not at all what I’m interested in,” insisted Diaz.

So does this mean there’s no hope for significant others to stay true? According to Diaz, the temptation can be too difficult to resist, which is why infidelity is an issue so many men and women are faced with.

“We are human beings, we are complicated,” said Diaz. “You cannot go through life without tallying up a few scars, you cannot go through life unscathed, it’s just what it is. It’s all meant to happen, take your lessons, figure it out, move on.”

But not all is doomed. While cheating is apparently inevitable, the actress explains anyone can tackle romantic hardships with the help of great friends. And no, we’re not talking about Ben & Jerry’s.

“I exist for all my girlfriends,” she added. “I am very, very, very fortunate; my friends are incredible and I am very lucky to have a lot of really solid, good friends — girlfriends and male friends — who I can just rely on.”

“We are tribal, we need our tribe,” says Diaz. “I have a bunch of little tribes all over the world that I pop to for a little bit of time, and then I move on and that’s the great thing about being mobile; a lot of my friends have kids and they are stuck, planted in one place, and I kind of get to pop into all the different little tribes around the world and hang out for a little bit.”

In case you’re wondering, Diaz doesn’t dish on whether she’s been a victim of cheating herself. Instead, she’s busy with her thriving Hollywood career, and of course, sharing giving advice on bodily functions and matters of the heart.
