The "B*tch Better Have My Money" crooner went all out with her costume, dressing up like the character Pebbles from the cartoon TV series/movies...with a twist. "They call me 'Thotty Pebbles,'" Rihanna says in a video clip her BFF Melissa Forde posted on Instagram. In it, the singer rocks a bone in her hair and a bone on her orange and black crop top, which matches her high-waist skirt.
Dancing next to her is her other BFF Jennifer Rosales a.k.a. "Ratchet Wilma," who is dressed up in a one-shoulder white dress, a huge white necklace and a Wilma Flintstone faux hairpiece. "#RatchetWilma @jennnrosales #ThottyPebbles @badgalriri #Majestys1stBirthday," Melissa captioned the video.
In another Instavideo, Rihanna can be seen twerking in a backyard in stilettos, with "Majesty" spelled out in huge stacks of colorful balloons in the background. Meanwhile, the birthday girl looked like she was having a blast too. The tiny tot's mom can be seen carrying her in to a room with a tiered Flintstones-themed birthday cake sitting on a table full of bowls of candy in a separate clip.
If you've taken a look through Rihanna's Instagram in the past year, it's no surprise she went all out for her little cousin Majesty's birthday (whom she calls her niece). The singer fell head over heels for the baby girl from the time she was born, posting pics of her on social media like crazy and even taking her to the Los Angeles premiere of her animated flick Home in March and the Grammys in February.
