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 yesterday (24.11.14) at the head office of Roc Nation, and 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.

Alongside a photo of the pair on Instagram, she wrote: ''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 s**t to suggest that it is in fact he that is the regular there. (sic)''

Rihanna also revealed her grandpa has a new girlfriend after he showed everybody at the meeting a photograph of the lucky woman.

She wrote on Instagram: ''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 (sic)''

It is thought that the singer was visiting her record label ahead of the release of her highly anticipated eighth studio album.

In October Rihanna revealed she was back in the studio as she tweeted: ''Burning candles inside of the studio, rappin n prayin (sic)''
