Rihanna's grandpa crashed her record label meeting and fell asleep on the couch!

Los Angeles - Rihanna's granddad crashed a meeting with her record label.

The Diamonds hitmaker was joined by her grandfather, Lionel Braithwaite, as she attended a meeting in New York on Monday at the head office of Roc Nation.

She revealed her excitable 86-year-old relative turned up at the offices with a mouthful of nuts and then started chatting to staff as if he knew them.

She shared a snap posing with him on Instagram...

im sitting in a meeting at the office yesterday, and this guy randomly walks in with a mouth full o cashews, talking to everybody callin em by first name and shit to suggest that it is in fact he that is the regular there. He then proceeds to take my seat, and starts showing pix of his new chick to errbody (she's saved to the wallpaper, yes he's 86). Eventually he passed out right on the couch in the middle of the meeting...smh... Bravo is da realest. #granddaughter
