It may not be Thursday, but Salma Hayek Pinault is already throwing it back. Today, she took to Instagram to share a funny photo of her and Susan Sarandon from the Women in Motion Prize Reception at the Cannes Film Festival, which took place two weeks ago in the South of France.

In the 'gram, the duo both stare at each other's cleavage. "Salma: 'Susan, you are bigger than me!' Susan Sarandon: 'Of course I am...' #cannes #friends #susansarandon," Pinault captioned the hilarious 'gram.

While you can't see their full ensembles from the 'gram above, both ladies looked gorgeous in the cleavage-baring looks. For the occasion, Pinault wore a light pink tiered gown that featured glitzy sequined straps, which she accessorized with a collar necklace that accentuated her figure. Meanwhile, Sarandon opted for a daring black off-the-shoulder dress.

Pinault was in Cannes to promote her upcoming movie, Drunk Parents, while Sarandon attended the festival with former co-star Geena Davis for the 25th anniversary of Thelma & Louise.
