Everybody is excited to see 2020 fade away and welcome the new year. Robert Downey Jr. celebrated 2021 by sharing this video on Instagram. Dressed all in white, kiddie pool full of dirty water, Van Halen's "Jump," red wig...

He wrote, "Who else is ready to#jumpon in to 2021 ? Here's to the new year...#happynewyear#2021(🎥@jimmy_rich)#rip@eddievanhalen"

Is this another "Ironman" sequel? What does this mean???
