The brunette beauty headed to the beach on Thursday, where she flaunted her sexy figure in a tiny tri-colored bikini. She even had a pair of black flippers in hand!

Before heading to the beach, Alba started her "lazy morning in paradise" with a cup of coffee, which she documented via Snapchat.

And judging from the other pics she's been posting on social media, it looks like Alba -- who's accompanied by her mother, Cathy, and best friend, Lauren Anderson -- has been having a blast on her girls' only getaway.

But the selfies didn't stop there!

On Friday, she posted a pic of herself rocking a fake flower crown, which was created by one of Snapchat's popular filters.

"Earth day," she wrote over another photo of her showing off her sun-kissed legs while lounging by the water.

Looks like she's been a "happy camper" the entire time!
