Jason Oppenheim is opening the door for Christine Quinn to come back to his Netflix show “Selling Sunset” … saying he’s down with her returning, but the buck doesn’t stop with him.

We got Jason in L.A. Thursday — and our photog asked him if a recent reunion with Christine and other cast members is a sure sign she’s gearing up to make a ‘Sunset’ comeback.

Jason tells us he would welcome Christine back with open arms and has no hard feelings … but explains it’s not his decision, rattling off the list of folks who would have to sign off on such a big move.

Waiting for your permission to load the Instagram Media.

Christine was a fan favorite on ‘SS’ for years … but after season 5 she left the show behind. Interestingly, some have said “Selling Sunset” hasn’t really been the same since she bounced.

There’s also been speculation Christine wants back in … this after she popped up recently at a promo event with Nicole Young, Mary Fitzgerald and Jason.

For her part, Christine hasn’t explicitly said she’s coming back to the show … and she last addressed the topic in November, when she told a fan on social media … “Sorry babe! Moved on to better things & sooo much happier.”

Fact is, Christine’s got a lot going on in her personal life … she’s going through a divorce and her estranged husband has been charged over alleged domestic violence incidents.
