Rain or shine, Gabrielle Union is going to rock a sexy bikini, and she doesn't care who doesn't like it.

The Being Mary Jane alum, 50, called out a troll who criticized her body while on the Who What Wear with Hilary Kerr podcast, as reported by PEOPLE.

Recalling the comment, she said, “Somebody said, ‘You’re old enough to be somebody’s grandma, why are you still in — like wearing swimsuits?’”

She quipped, saying, "I'm like, 'First of all, they're not just swimsuits. They are thongs."

Then Union stood her ground. "And you're gonna see these cheeks until my ass literally falls off, and I might just wear a bikini in the casket."

Adding more punch, she said, “I don’t know. That just might be for you, for that one commenter… This is for you b—… It’s just gonna be like, me in a thong, like, ass-up in the casket.”

And buns out has been the theme as of late for the actress. Back in June, while in Miami for the premiere of her latest Netflix film, The Perfect Find starring opposite Keith Powers, she donned a sultry gown that accentuated her derrière.

She was the center of attention as she walked the red carpet while wearing a sheer gown by French designer Burc Akyol. According to Harper's Bazaar, the dress featured a black satin turtleneck bodysuit and cape-like sleeves made of white chiffon. But the main attraction was the back of the gown, designed in a high-cut thong that made Union a bootylicious masterpiece.

Union took to Instagram to share her excitement of the evening in a post that kept her fans wanting more. “Just enough to get a glimpse 😉," she wrote in the caption.

Her hubby Dywane Wade jumped into her comment section adding, “Damn 🔥🔥🔥🔥🔥”.
