On Tuesday, Mariah Carey showed off her post-baby bod with a fun TwitPic, in which the ‘Daydream’ singer can be seen splashing about in the ocean.

“Ocean work out!,” Carey tweeted. “It’s been a loooong time since I’ve been in the ocean (said like “OPEN”in cruise control).”

No word on where Carey, who gave birth to twins Morocco and Monroe in April, is vacationing, but it’s still a nice glimpse of the pop diva, who hasn’t looked this good or happy in quite some time.

Check out a larger version of the TwitPic below.
