Usually, our “O” faces are meant to be private, but Real Housewives of Beverly Hills star Kyle Richards is putting hers out there for the world to see — and no, she’s not faking it. But we don’t mean that “O” face — that’s to be kept between her and hubby Mauricio Umansky. We’re talking about the face most women make when they’re applying mascara!

Reality stars Kyle, Carmen Electra, and Kristin Cavallari all took part in Benefit’s new video entitled, “Real Women Don’t Fake It,” in honor of the brand’s best-selling “They’re Real” mascara’s two-year anniversary.

Kyle makes no bones about the fact that“They’re Real” is her top pick when it comes to her lashes.

“I’ve loved ‘They’re Real’ since a makeup artist used it on me at a shoot,” Kyle says. “I was doing this scene where I came out of the pool, and I figured coming out of the water it would be smeared all over my face. It wasn’t, and I thought, ‘OMG, I need this mascara!’”

From the sound of things, its waterproof strength will be put to the test during season four of RHoBH, which kicks off November 4. By all accounts, we’re prepared for more waterworks than ever.

Shooting the new season was “very anxiety-provoking,” Kyle has commented. “I have had many sleepless nights and many tears doing this show.”

But at least her makeup always looks great, right?
