'Oppenheimer' star Robert Downey Jr. admits he was beyond 'jealous' of pal Rob Lowe in high school

Robert Downey Jr. admitted to his pal Rob Lowe that he was beyond "jealous" of him when the two attended high school together.

"I want to say I was jealous, but that's not deep enough," Downey told Lowe of his professional prowess in high school. "I want to say that I didn't understand how anyone could get where you were. Let alone, still have attendance in [school]. It just seemed like there was something so high functioning going on, that there was no point for me to even attempt to understand it."

Lowe, who referred to himself as a "little snob b----" at the time, joked "he couldn't possibly be bothered with high school theater," like Downey, since he was a working actor at the time. Lowe remembered sometimes walking past the bulletin board and seeing a message from his agent to phone him.
