What are Tamra Judge and Vicki Gunvalson up to? That's the question fans are asking after they each posted a photo of themselves filming on Sunday.

In the Instagram picture, the former "Real Housewives of Orange County" stars appear to be enjoying a glass of wine together and chatting while sitting at a kitchen counter -- a pretty normal sight for the ladies. However, in the left corner of the photo, a cameraman can be seen filming them.

"How’s your Sunday?" Tamra captioned the photo along with the hashtag #lifeafterhouswives.

Meanwhile, the OG of the OC wrote, "Just another Sunday night," followed by the hashtags #lifeafterhousewives #cantkeepusdown and #woohoo.

Tamra further teased fans on her Instagram story writing, "You thought you saw the last of us?" over a video of herself and Vicki together.

Neither of the reality stars specified what they were filming, but it does come at an interesting time. They both publically revealed that they would not be returning to "RHOC" for Season 15 in January.

Vicki, who had been a part of the popular Bravo franchise since the beginning in 2006, made her announcement on Jan. 24. Tamra's exit announcement came just one day later.

Fans speculated a few different reasons, including that the duo could be filming a spinoff show. Based on an insider, though, unless they are filming for "RHOC," it could be difficult, but not impossible, for the ladies to get a new television project off of the ground.

"Vicki and Tamra have a one-year non-compete clause in their contracts," an insider explained.

It's not a complete on-screen blackout for the ex "Housewives" though. The source goes on to reveal that the two are allowed to appear on another show if they "get special permission" first.

There is, of course, always the chance that they could be filming for "RHOC" in order to close out their storylines, which is something that Tamra was initially offered but turned down.
