Gabrielle Union Makes Us Jealous With Her Bikini Body

It's hard to not be envious of Gabrielle Union.

The 40-year-old actress showed off her hot bikini body in a series of Instagram pics this week that set (our) hearts racing.

Captioning the photos "Work hard. . . Laugh harder #urbancowgirl," the "Being Mary Jane" star looked happy and healthy in the two snaps which showed Gabi up close and smiling in a blinding white bikini and in a full-body shot which revealed her super toned legs and rock-hard abs. (Now that's one excellent reason for joining a spinning class.)

The former "Flashforward" star wore no makeup –a habit the "Bring It On" actress likes to flaunt in our faces on her Instagram account. Hey, we would go makeup-free too if we had Union's flawless face!

But the gorgeous celeb didn't come by her smooth skin by chance; Union told the Huffington Post that she is a huge fan of sunscreen.

"It’s not even just about slapping it on once and calling it a day, regardless of your skin tone you also have to reapply. Someone described it to me once as that one application need to be enough to fill a shot glass and that visual stuck with me and was easy to remember. You have to put on enough, roughly every two hours, or it doesn't do you any good.

If you can't remember to protect your skin for health reasons, do it for vanity as the sun can be really aging and I don't know any women or young girls who want that later on in life."

Words to live by!

We love these ladies:
