Somber RiRi returned to her hometown of Barbados for Gran Gran Dolly’s funeral wearing an all black dress and dark red lips.

She tweeted earlier today, “Ima try to be a big girl now” along with a Tweetgram photo that read:

“grangranDolly you are gonna have the BEST PARTY today #allblackerrthang! And I’m gon try to hold it all in, try to hold back my tears”

The “Birthday Cake” singer also tweeted another photo of herself looking very sad with a bottle of alcohol close to her lips. The caption read, “I had to!!! Sorry granny.”

We hope Rihanna is hanging in there and staying strong. Losing a family member is one of the toughest challenges anyone can endure, but we believe that she will get through this difficult time.
