“Selling Sunset” star Christine Quinn missed the reunion show Sunday because she says she had COVID, which makes this photo of her on a film set Tuesday very interesting.

We’ve obtained a photo of Quinn on her phone, while crew members stand around her to prepare for a shot. What’s interesting … it’s ‘RHONJ’ star Melissa Gorga seated next to her.

Unclear what this gig entails, but her rep told us Monday Christine had to miss the “Selling Sunset” reunion over the weekend after testing positive for COVID on Saturday.

Of course, the CDC recommends … someone who has tested positive for COVID should isolate for at least 5 days. Quinn’s obviously not doing that, and while one of the crew members is masked up, Christine isn’t.

If you’ve followed the most recent season of “Selling Sunset,” you know Christine is the show’s villain — so when TMZ broke the story she’d have to miss the reunion because her rep said she had COVID, a ton of the show’s fans thought she might’ve been faking it to avoid confrontation with the other cast members.

At this point, we’re hoping she was faking COVID, cuz showing up to work just a few days after a positive test doesn’t seem to be a very safe way of doing business.

We reached out to Quinn’s rep for comment … so far, no word back.
