Britney Spears is up to something fishy!

The songstress took to Twitter on Thursday to show off her newest accessory: A mermaid tail! Also included in the pic: her two boys (Sean, 9, and Jayden, 8) and her perfect abs. Seems like the life of a Vegas superstar agrees with her!

"The mermaid life!" she captioned the photo.

The singer has been performing her "Piece of Me" tour at Planet Hollywood in Las Vegas since December 2013.

Brit-Brit's had it rough over the past few years: Relationships have fallen apart, singles have fallen flat, and she's fallen down. But it seems like she's turned a new leaf recently. Or a new scale, rather (fish jokes!).

And she's not the only celeb living that #mermaidlife: Kim Kardashian recently Instagrammed a pic of baby North and her cousin Penelope donning tails with a fellow sea creature, as well as a photo of the unnamed woman swimming.

"Mermaids are real," she wrote.
