"Aloha from Hawaii," Britney Spears tweeted on Thursday after spending the afternoon at the beach with her sons and boyfriend in the tropical island.

The singer posted a photo of herself wearing a bright blue bikini in what appears to be her hotel room. She also uploaded a group shot of herself in pink with Sean Preston, eight, Jayden James, seven, and her sweetie David Lucato on the beach.

Earlier this month, the pop star was spotted wearing a ring on her wedding finger, sparking rumors that she was engaged. She recently attended her younger sister Jamie-Lynn's wedding in New Orleans, La.

"Yesterday was magical. So happy I could be a part of my little sister's big day. Congrats," she tweeted on March 15.
