'Friends' is the gift that keeps on giving, with this latest piece of trivia delighting fans of the sitcom, and fans of Billie Eilish.

The 'Friends' reunion is one of the most highly anticipated TV get togethers possibly ever.

Until it happens, little behind-the-scenes facts like this will have to tide over fans.

It has emerged that Maggie Baird, Billie Eilish's mom, appeared on the show, back before the popstar was born.

It wasn't the only show Baird popped up in during the '90s-'00s as she also has credits in 'The X-Files' and 'West Wing'.

The episode she appears in is "The One Where Joey Loses His Insurance". The episode sees Joey (Matt LeBlanc) develop a hernia and struggle to land a job, which he needs to secure health insurance.

Among the auditions he goes for is an ad for dog food. Baird is the casting director.

She's unimpressed when Joey refuses to lift the large bag of dog food (due to his hernia). He suggests he point to the bag instead.
