Karrueche Tran birthday flowers 3 wheelers chris brown

Who says adults can't play with toys on their birthdays?!

Karrueche Tran turned 26-years-old over the weekend, and Chris Brown's lady love decided to celebrate by riding 3-wheelers with pals to a party at Toxic nightclub in Hollywood.

The model was scantily clad in white shorts and a matching crop top, and she was oddly donning a grass skirt as well. Maybe her bash was Hawaiian-themed?

We wonder if her beau called to wish her a happy birthday from prison? We think Breezy is going to be in the slammer for a while, so he better hope his girl doesn't move on to someone new in the meantime!
