It's now November, which is about the time when we wish we could move to Hawaii for, oh, about the next five months. So we're extra jealous that three Real Housewives of Orange County stars are currently there together.

Tamra Barney, Heather Dubrow, and Vicki Gunvalson are all hanging out together on Oahu this week, with Tamra posting a photo to Instagram of the three of them in Waikiki.

"Last three standing @heatherdubrow @vgunvalson @tamrajudge," Tamra captions the shot.

Indeed, Tamra's caption appears to confirm the rumors that Gretchen Rossi and Alexis Bellino won't be returning for Season 9. Lydia McLaughlin revealed this week that she also won't be returning.

So what exactly are the three ladies doing in Hawaii, other than having fun in the sun? Well, Heather has been filming a role on the CBS cop drama Hawaii Five-O, which required her to sport some fake blood. And Tamra and Vick flew out to see her after she wrapped up the show on November 5.

"It's a wrap!" Heather captions a collage of photos of herself from the show's set. "Now off for some fun with @tamrabarney @vgunvalson in Hawaii! #RHOC."

Later, Heather posted a photo of herself with the two women, which she captioned, "Having fun in Waikiki! @tamrajudge @vgunvalson #RHOC."

And Tamra tweeted on November 5, "Good morning. Up early and it's not to work out! Headed to Hawaii with @vgunvalson @HeatherDubrow . #H50 #Bravo #rhoc #season9."

As you can see from Tamra's last hashtag, it appears that Bravo's cameras will be rolling during the trip, meaning they've already started filming Season 9. But which other ladies will be added to the cast this season? We suppose we'll have to be patient. And don't forget the sunblock, ladies!
