The two hunks-of-men were spotted chatting in front of The Prime Grill -- the site of Paris Hilton's greasied birthday blowout -- where the former WWE man-in-tights asked Reynolds, "Have you officially come out of the closet yet?"
The ripped Reynolds laughed off the remark as his ladyfriend asked The Rock, "Have you??" Someone's playing matchmaker! The Rock replied, "Tomorrow I will."
TMZ will cover the official announcement ... just as soon as we hear from The Rock. Don't wait up.
