Cassie showed once again exactly why she is P. Diddy's (rumoured) number one lady, at the premiere of Killing Them Softly at the Cannes Film Festival.
The King of Hearts singer looked absolutely stunning wearing a Black Swan-esque floor-length, black lace gown that accentuated her gown perfectly. With her hair worn out in loose waves and scraped to one side, there's no denying Cassie looked like a million dollars.
After wowing photographers on the red carpet, Cassie later headed on down to Diddy's star-studded yacht party on the Harbour where she mingled with the likes of Rita Ora, Kim Kardashian and Kanye West.
Cassie has been enjoying her time in Cannes for the last week with her rumoured boyfriend and mentor Diddy.
As stunning as she is, we're questioning why Diddy is keeping her on the down-low! Your thoughts on Cassie's gown? Check it out below.
