PASADENA, Calif. — Something mysterious is going down with the Rolling Stones concert at the Rose Bowl on Thursday night.
Robert Downey Jr. has promised it's going to be big, posting a cryptic, trippy video on his official Twitter and Instagram accounts Thursday afternoon — filmed against a galaxy backdrop with the Rolling Stones logo at the top.
The tweet had one word: "Tonight." In the video, Downey Jr. said he was "bubbling with anticipation."
But he was hilariously secretive.
"My gosh, I have inside me a riddle that I have to share. What do the Rolling Stones, NASA, and the Rose Bowl and the ruling planet of my birth sign all have in common?"
He never answered the question.
"Folks used to say to me, 'How do you keep an idiot in suspense? I'll tell you tomorrow.' " he joked. "Well you don't have to wait. Because it will all be revealed tonight. Oh, my God. This may be the most exciting thing I have ever done."
Downey Jr. then started singing the Stones classic "Wild Horses," before he was mock-run over by digital horses.
A couple of hints: Downey's birth sign is Aries, and that sign's ruling planet is Mars. And he addressed the tweet to the Stones, NASA, and the Jet Propulsion Laboratory, which is near the Rose Bowl in Pasadena, California.
The Stones Twitter account hints that the Avenger would be hitting the stage, tweeting, "Maybe we'll see you tonight then…?"
The NASA account stirred the mystery as well, tweeting, "Can't get no satisfaction till you know what this is all about? Stay tuned!"
