The singer just shared some fun videos of her Hawaiian getaway, and she looks like she's having a blast on the island. Britney's showing off her body in a skimpy red bikini, making angels in the sand and playing in the ocean.

Britney is definitely practicing aloha ... saying she likes the sounds of the waves at night and listening to people laughing from her hotel balcony. She adds, "there's a togetherness here and it's endless!!!"

As we first told you ... Britney and her boyfriend, Sam Asghari, hopped on a private plane to Maui last week in the wake of her explosive court testimony on her conservatorship, and they looked like they were having a great time right out of the gate.

Remember, Britney claimed she's been threatened to have her Maui vacations denied if she doesn't go to therapy, and she complained about feeling trapped by the conservatorship.

Britney and Sam have been all smiles since they boarded their private flight to Hawaii ... she previously posted some funny videos from their jet, playing around with filters and acting silly.
