Long before her acting career, Natalie Portman was belting out pop medleys for a good cause!

"There were, like, eight people who would come in and out. We would perform at, like,... Earth Day," the 35-year-old actress continued. "I was really dorky, OK?"

And of COURSE, host James Corden was able to dig up some old tape of Portman and the band, which was as adorable as it was eco-conscious -- and young Portman had pretty good pipes too!
