Now that Kim Kardashian is single again, she's putting herself back out there in a big way: by posting sexy pix of herself on Twitter!

The reality starlet, who's got over 3 million followers, posted a shot of herself sunbathing atop a yacht in Miami (where she's shooting Kourtney & Khloe Take Miami) and another of her blowing a kiss to the camera!

"Another beautiful Miami day on the boat," Kim tweeted, seemingly in great spirits despite her very public breakup.

With a body like that, though, we have no doubt that she won't be single for long!
