InstagramIntroducing: "Thotty Pebbles" aka Rihanna at her cousin Majesty's first birthday party.
The Grammy winner dressed up for the Flintstones-themed soiree along with her pals Jennifer Rosales (who opted to go as "Ratchet Wilma") and Melissa Forde.
Forde shot multiple videos on Instagram from the lively bash, including several of Riri twerking to a DJ set in a backyard filled with balloons and party décor.
Leave it to her and her favorite ladies to turn up at a baby's birthday, right?
But it wasn't all winding and grinding in honor of Majesty during the daytime affair…
One adorable clip also shows the partygoers singing "Happy Birthday" to the one-year-old as she checks out her massive three-tiered cake for the very first time.
The "Bitch Better Have My Money" singer has posted a slew of pics of her time with baby Majesty and has made no secret of the fact that she's head over heels for the little one.
In fact, less than one month ago Rihanna posted a photo of the cute tot dressed in a bikini and matching sunglasses and wrote, "How is this happening so fast???! Hey lil mamaz! Her Maje$ty!!!"
And right after the sweet snapshot, she shared a video of Majesty saying hello on camera and giving a kiss to Riri via iPhone since the singer was traveling for work.
"The best mornings start like this! I'm spoiled!! Aunty misses you baby!!!"
Sounds like their reunion this weekend was worth the wait!
