They're not afraid to flaunt it.
Salma Hayek was feeling nostalgic on Monday, when she posted a picture from last week's Cannes Film Festival. The selfie features her and her close pal Susan Sarandon staring at each other's ample cleavage, with the Grown Ups 2 actress conceding defeat to 69-year-old Sarandon.
"Salma: 'Susan, you are bigger than me!'" Hayek captioned the photo. "Susan Sarandon: 'Of course I am...' #cannes #friends #susansarandon."
Both ladies looked gorgeous at the Women in Motion Prize Reception event last Sunday where they posed together on the carpet. Hayek sported a curve-hugging tiered gown, while Sarandon chose a glamorous knee-length dress for the occasion.
But the ageless Thelma & Louise star wasn't the only celeb who got up close and personal with Hayek's assets at Cannes. Last week, the 49-year-old actress shared this shot of Chloe Sevigny licking her chest.
Prior to Hayek's hilarious selfie, Sarandon had jaws dropping when she attended the Cannes premiere of Money Monster, sporting a plunging navy dress with gold buttons. The racy gown also featured a sexy slit.
Of course, this isn't the first time Sarandon's cleavage has made headlines. In February, she got into a Twitter feud with the always outspoken Piers Morgan, who criticized her after she wore a bra top to the Screen Actors Guild Awards.
"Would Susan Sarandon wear this to a funeral? No," Morgan tweeted. "It was thus horribly inappropriate for an In Memoriam tribute."

The Oscar-winning actress fired back by tweeting a throwback photo of herself in a bra.
"Today’s #TBT is dedicated to @piersmorgan," she joked about The Rocky Horror Picture Show screenshot.
"I love the solidarity of women that came forward," Sarandon also told ET exclusively about the spat in February, referring to the large number of women who flashed their cleavage on Twitter in support of the actress. "I was very happy that all the gals came forward."
"[Morgan] has way too much time on his hands, obviously," she added.
