Salma Hayek has long had one of Hollywood's most envy-worth bod, but she's not above making a little fun of herself either.

The brunette beauty was at the Cannes Film Festival when she ran into her pal Susan Sarandon who was wearing a low cut outfit that made eyeballs fixate on her cleavage. Salma, too, was wearing a revealing gown.

What are a couple high-powered ladies to do? Compare boobs, of course.

On May 24, Salma shared a funny photo of her and Susan taking a glance at each other's goods, so to speak. The Mexican film star recounted the conversation as her caption.

Salma: "Susan, you are bigger than me!" Susan Sarandon: "Of course I am..." #cannes #friends #susansarandon

"Susan, you are bigger than me!'," she jokingly asked, to which Susan apparently retorted, "Of course I am…"

We're not sure which of the two was crowned the eventual winner.

The great cleavage comparison actually occurred last week while the women attended the Women in Motion gala awards. There, Susan donned a little black dress with a plunging neckline. Salma, who was with her husband, showed off her ample assets in floor-length pale pink gown with spaghetti straps.

Salma only posted the image on Tuesday, although the snap was taken over a week ago. She shared a few photos from the event in real time.

For Salma, though, she seemed to really revel in her body's assets while in the south of France.

The actress shared a humorous image of Chloe Sevigny to her Instagram last week, as well. In it, Salma wears a low cut dress as she puts her hand is on Chloe's chest. Chloe, meanwhile, appears to lick Salma's sun-kissed chest.

"#Beautiful #sunset in #cannes #chloësevigny #stellamccartney #boucheron," Salma captioned the image.

Chloe shared the same image to her Instagram the same day, saying, "Viva la Mexico I [heart] actresses #salmahayek."

At Cannes, Salma promoted her upcoming movie, "Drunk Parents." Susan attended the festival with former co-star Geena Davis for the 25th anniversary of "Thelma & Louise."

It was clearly the breast week ever for Salma.
