Well it turns out…
That's not the case.
While many assume she became a celebrity nanny to become closer to the stars, an insider says:
Rihanna doesn't turn 24 until February 20, but she had one hell of a party at the Hearst Mansion in Beverly Hills on Monday night!!
The soiree was Caribbean-themed (of course), so guests enjoyed a tropical dinner with Sprinkles cupcakes adorned with little Barbadian flags.
Yummy!! Sooo perfect for her!!!
They all danced to bass drum Caribbean beats and took keepsake photos in a photobooth that came with fun dress-up clothes!!
THEN!! The grand finale came out at 2am — 20 bottles of Armand de Brignac Brut Gold Champagne with a custom birthday cake with an image of Rihanna in a red bikini bottom on a seashell. LOVE IT!!
Happy Early Birthday, RiRi!!!
