Mariah Carey is ready for the beach!
The new mom squeezed into a black one-piece bathing suit today, posting the above photo just moments ago on her Twitter -- saying "Ocean work out! It's been a loooong time since I've been in the ocean."
Carey, who gave birth to twins back in April, hit the surf for the first time since having a baby, showing off her slimmed down frame.
Lookin' good Mimi!
