Carey was leaving an after party at popular Los Angeles hotspot Poppy with her boyfriend, Brian Tanaka, when she was asked about the mix-up.
“It wasn’t on purpose!” Carey can be heard saying as she heads to her car.
Carey explained what happened on Twitter, writing, “Got caught mingling on the way to the loo during a commercial break.. took the first seat available, happens to be right next to Steven Spielberg 😮😮 Cut to next commercial break, guess who comes back to her seat…”
She concluded the story by writing to Streep, “You can take my seat any time! 😂😂💖💖💖💖”
(me) Dear Meryl, please forgive me!!! 🙌🙌
(MERYL STREEP) You can take my seat any time! 😂😂
