THIS would be the dopest couple ever! I’m so excited at the potential! LOL. The way it went down, though…I’m sort of inclined to think it’s just a late business meeting. Find out who the famous actor is below.

Rihanna — and her security team — stopped by Ashton Kutcher’s swanky L.A. house for a little late night visit Wednesday.

According to the photographer, the “Birthday Cake” singer got to Ashton’s home right around midnight … and didn’t leave ’til roughly 4 AM.

As we previously reported, Justin Bieber recently checked out Ashton’s $10 million bachelor pad on his high-end real estate hunt … but we’re guessin’ Rihanna wasn’t there for an open house.

So far, no comment from Rihanna’s rep.
