In case you were wondering what was back there: The Stay singer also posted a photo of her derriere Cheeky! In another shot Rihanna pulled her bikini out flashing a bit more than expected From the front, Rihanna shows off ample cleavage and in another shot taken from behind, a G-string design shows off her pert derriere for all to see, as she stands in what looks to be a mystical waterfall. Whether or not the ladies were competing for any sort of attention from the Mechanical Dummy singer is uncertain, but if nothing else it’s an eerie coincidence. Perhaps Karrueche was soaking up the sun as a way to recover from the night before. Girls night out! Previously, on Friday night, Karrueche hit the town to enjoy a night out at the Laugh Factory with gal pals Amber Rose and Christina Milian Supporting! Priscilla Ono, Amber Rose, Karrueche Tran and Christina Milian (L-R) were all at the Hollywood comedy venue to see their friend Amy Schumer perform The pretty model spent the night out and about with a troupe of other famous ladies, taking in the best of LA’s comedy at the world famous Laugh Factory. The group of girls seemed to be having a whale of a time watching their comedian friend Amy Schumer perform, snuggling together in their sexy, revealing outfits to pose for happy snaps. Karrueche was adorable in a white flowing strapless dress, which featured billowing sleeves and gave her somewhat of a prairie girl aesthetic. ‘You’re no angel either baby!’ Karrueche enigmatically captioned this photo of herself in her gorgeous prairie girl dress whilst out and about with the girls on Friday ‘Getting chrae on New Years Day!’ Karrueche posted this happy snap of herself eating Chris Brown’s tongue on New Years day, suggesting there is happiness in the Tran/Brown camp And they weren’t just silent spectators, either. As evidenced in an Instagram video, Christina Milian and Amber Rose took the stage at one point to introduce their comedian friend Amy Schumer.
