Cara Delevingne, 21, showed off her rockin' body in a pair of skimpy bikini bottoms as she played in the surf with her alleged 35-year-old girlfriend Michelle Rodriguez.

They even displayed some heavy PDA in the ocean in Cancun, Mexico.

(See the photos!)

They've only been together for a few months, but it appeared as though the hot new couple were still very much in the honeymoon phase when they were photographed.

Cara and Michelle reportedly stayed at the Mayan Riviera resort of Tulum.

Both Cara and Michelle have been documenting their vacation by posting photos on their Instagram accounts.

On Saturday, the "Fast & Furious" star uploaded a photo of herself in a snorkel while holding a turtle.

She captioned the image: "I'm in love with Tulum."

Meanwhile, Cara posted a photo of her feet in the golden sands, writing: "Mmmmmmmm best feeling ever."

Sadly, their romantic getaway came to an end on Friday, when the duo was spotted collecting luggage from a car.

What do you think? Is Cancun, Mexico a good place to enjoy a romantic vacation?
