The Week's Best Style Moments: Gabrielle Union, Tichina Arnold And Maya Rudolph (PHOTOS)

With tons of star-studded events and the Cannes Film Festival in full swing it was bound to be a week filled with fabulous fashion moments.

We're used to laughing at Maya Rudolph's comedic genius on "Up All Night," but all we could do was cheer after seeing the actress in a sassy leopard print dress and bold red lip this week at NBC's Upfront presentation.

"Happily Divorced" actress Tichina Arnold stepped out in a bold orange dress to attend an event honoring Betty White.

Speaking of white (the color, not the gal!), Gabrielle Union was spotted wearing a crispy white frock by fashion designer Rachel Roy. And Rachel also made our list this week after attending the American Ballet Theatre's Spring opening gala in a 50s styled dress cinched at the waist with a leopard print belt and her adorable daughter Tallulah on her arm.

As for the Cannes Film festival, Eva Longoria stunned on opening day in a Marchesa gown and Jada Pinkett Smith was gorgeous in a green Alberta Ferretti number at a photo call for her film "Madagascar 3."

Check out those lovely ladies and the rest of the well-dressed stars in the slideshow below.
