Carlton's Tame Party and a Maybe Chess Game | The Real Housewives of Beverly Hills Photos

Two Birthdays, One Big Fight

Yolanda meets with her ex Mohammed to discuss throwing a big going away party for Gigi before she heads off to NYC.

Not only are Yolanda and her ex civil, she's also a big fan of his current girlfriend, and more than happy to let her help out with the event planning. How mature!

Meanwhile Kyle's daughter is ready to hang out with her friends, but Kyle is a little worried about their plans. What if they other kids' parents haven't been as diligent as Miss Richards?

But Alexia learned from a pretty good pair. She's going to make all the right choices (or at least she swears she will).

Carlton's planning for a large work party with her husband. It's going to be slightly less understated than their pool party. . .

Besides not inviting strippers to this shindig, Kyle's been uninvited. Mauricio is welcome, but we can't imagine he'll show without his leading lady in tow.

Joyce gets together with a Queen of the Universe pal to work on her fitness.

Lunge like the whole universe depends on it ladies!

David Foster sits down to quiz Yolanda for her upcoming American citizenship test. Will she be able to pass and prove her allegiance to America?

This is the face of a woman who can't bear to memorize any more facts about the U.S. government.

At her party, Carlton pulls Lisa aside to apologize for the fight between her and Kyle at Ken and Mauricio's birthday party.

But Lisa wants to make sure that Carlton knows she doesn't agree with her decision to bring it up, though she sees both sides of the ladies' disagreement.

When talk of Carlton's past growing up in Africa comes up, she breaks down. She might be British, but Carlton isn't afraid to get emotional.

On the way out, Lisa and Ken run into to Kim, who still isn't over Lisa's missing her daughter's graduation party.

Turn about is fair play, when Lisa asks Kim why she missed the boys' birthday, Kim swears she has the pictures to prove she was away.

Brandi arrives but is feeling a bit under the weather. She's had an allergic reaction and is a bit worried about her throat closing up.

Carlton is shocked. We wonder if she has any spells to help heal her pal.

Brandi fills Kim in on what she missed at Ken and Mauricio's birthday party -- which was Brandi's ex-husband's ex-girlfriend once again serving her drinks.

Kim's a little incredulous about Lisa as well. She sees Brandi's side of the Scheana situation, and still isn't over Lisa skipping Kimberly's graduation.

Lisa is busy prepping for a photoshoot, with her full-scale glam squad (including Stassi) along for the ride.

Lisa enlists Stassi to stop by her house and help her with the photoshoot, and Stassi's thrilled to take in all the fanfare.

She's less than thrilled to learn she's not trusted enough to be in charge of jewelry pick-up. But with baubles that irresistible (and expensive) who could you truly trust?

Kyle and Brandi go for a hike in the canyon. Hopefully Brandi can survive the walk injury free!

Brandi confides in Kyle that she's starting to feel played by Lisa. She googled Bobby Fischer and now she's wondering if she has indeed been checked.

Kyle confides in Brandi that even though she's friendly with Lisa once again, she's not fully trusting of their friendship. Kyle says she'll always know the kind of friend Lisa is.
