amFAR Gala 2016: Katy Perry and Orlando Bloom, Bella Hadid, Helen Mirren and More Glamour

Look at all the pretty people!

Once again, the 23rd annual amfAR  Cinema Against AIDS Gala in Cannes brought out the glitz and glamour, with models and celebrities dressing up to the nines to walk the red carpet at the famous Hotel du Cap-Eden-Roc.

Katy Perry and her beau Orlando Bloom were there, although they arrived separately and did not pose together on the red carpet (damn them!) They have been flitting about Cannes, canoodling on yachts and whatnot and basically putting an end to rumors their romance may be on the rocks.

Perry wore a right red floor-length dress with frills, with Harry Winston cluster diamond chandelier earrings and a Lotus diamond ring, while Bloom looked dapper in a tux. Katy also performed at the event that helps support the global fight to end AIDS.

Also in attendance was the lovely Helen Mirren, who wore a black dress with metallic detailing, along with a Harry Winsston Lily diamond necklace and radiant yellow diamond earrings. This was the first time the 70-year-old attended the star-studded event, and she admitted, “This is so glamorous, it’s my first time, I’m quite intimidated.”

As for some of the supermodels there, the stunning Bella Hadid covered up a bit after flashing skin earlier in the week at the Cannes Film Festival, while Karolina Kurkova looked pretty in lavender, wearing the Harry Winston Secret Cluster Perfume Bottle Necklace, exclusively set with aquamarines and sapphires.
