After giving birth to eight babies, Kate Gosselin is ready to show off her bikini body on the new cover of PEOPLE.

The reality TV mom admits that now that her children are all in school, she has more time to exercise and is "the most fit I've ever been."

"I've worked really hard! Haven't I earned the right, at this point, to look good?" she says.

In the interview, the 'Kate Plus 8' star admits to having a tummy tuck after the birth of her sextuplets, but denies those botox and breast implant rumors, saying all she's done is eat healthier and purchase a great push-up bra. Flaunting her body is just another way to show ex-husband Jon Gosselin what he's missing out on.

After a scandal-plagued separation, Kate's divorce from Jon was finalized in December 2009.
