Courteney Cox Sends Matthew Perry The Most Monica Of Birthday Messages

Courteney Cox went all Monica Geller as she sent a birthday message to her Friends co-star Matthew Perry on Instagram on Thursday. 

The actor, who played Matthew’s on-screen wife on this hit US sitcom , slipped in one of her character’s famous catchphrases as she dedicated a post on her Story to him. 

Sharing a throwback image of the two of them together, Courteney wrote: “Happy birthday to one of the funniest people ‘I KNOW’,” along with a love heart emoji. 

Monica was famed for her “I KNOW!” catchphrase during Friends’ 10-year run, often uttered when she was proven right about something.
