According to FemaleFirst, the rapper approached the star during the party at Hard Rock Hotel for the launch of his album Curtis, last Saturday night.
A source stated, "50 played a few songs and then made straight for Paris. She was laughing and unashamedly flirting and couldn’t keep her hands of him. He nuzzled up to her and they cuddled."
The couple had a little fling last year in Cannes at the Film Festival.
