Britney Spears makes a splash in neon ʙικιɴι during honeymoon

It may be “raining cats & dogs” during Britney Spears and Sam Asghari’s tropical honeymoon, but the pop princess isn’t letting a little bad weather get her down.

Spears posted a video of herself splashing in the surf on Instagram Monday, clad in a neon green-and-pink Doll ʙικιɴι top ($35) and leopard-print Yandy bottom ($18).

Doll appears to be one of the 40-year-old superstar’s favorite swimwear sources, as she modeled a similar style on social media last month while showing off her post-wedding haircut.

While there wasn’t a rain cloud in sight in the clip, Spears bemoaned in her caption, “Of course on my honeymoon the suns [sic] not out !!!”

She also said she’s been pᴀssing the time by watching “How to Lose a Guy in 10 Days” — her “fave comedy of all time” — and snacking on fruit, “cause its too H๏τ and muggy to eat H๏τ food !!!”

Of the latter, she described it as so tasty, “it melts and puts me in bliss.”

It seems Spears and Asghari, 28, didn’t travel to the tropical destination solo; the Grammy winner also shared a video of her husband carrying the couple’s Australian Shepherd, Sawyer, on their private jet — presumably en route to their honeymoon.

The “Toxic” songstress married her longtime love at her former home in Thousand Oaks, Calif., on June 9. Spears walked down the aisle in a custom dress and veil from Atelier Versace, which also provided the groom’s tuxedo.

After the “I dos,” the duo danced the night away alongside celebrity pals like Madonna, Paris Hilton and Selena Gomez, with the bride partying in three different Versace reception looks.
