The Stars Come Out for Rihanna's Diamond Ball and So Does Beyonce's Undergarments! [PHOTOS]

Rihanna has had one of the busiest weeks known to man! Earlier this week she took the fashion and beauty world by storm first by launching Fenty Beauty, a new cosmetics line, then at New York Fashion Week ion the runway! Just last night she hosted her third annual Diamond Ball to benefit her charity, the Clara Lionel Foundation , and boy did the stars turn out!

In attendance were Lil Kim, Cardi B, Future, LaLa Anthony, Jay-Z and Beyonce just to name a few! Get a load of the glamour in these photos and the peek we all got at Beyonce's undergarments!

I'm not mad at Beyonce for wearing some support under her clothes AT ALL! She's got a thicker frame that still needs to look smooth under fitting garments. What tickled me was her breasts looking like she forgot to feed the twins, or pump, before she left the house! Cardi B looks amazing in her ball gown! It's refreshing to see her in something other than club clothes! Let's talk about these other fashion decisions in the comments below!
