Adele still has nightmares about calling Jennifer Aniston by her "Friends" character's name during an awkward restroom encounter.
The British singer was stopped from entering the ladies room at a New York venue by the actress' security team, but when Aniston realized who she was she waved Adele in to the restroom.
The two ladies struck up a conversation from their separate cubicles – and nervous Adele was left mortified when she mistakenly called Aniston, Rachel.
She tells British TV host Graham Norton, "We went into the cubicles and sat down and I could hear her, ';Pssssssst.' And through the cubicle she said, ';So how are you, honey.' And I just called her Rachel! I said, 'I'm fine thank you, Rachel.'"
