Miley Cyrus is busting out all over. The teen star is finally beginning to develop the body of a woman, and Miley is damn proud of her cleavage, and she’s telling girls to love their curves, too.

Miley, who turns 19 this month, has been on a bit of a crusade lately, ever since her on-again, off-again pal Demi Lovato has been taking heat for gaining some weight.

Cyrus, who has gotten more than her fair share of grief from Internet haters, lashed out at snarky bloggers who have been haranguing Lovato.

“@ddlovato AMEN! I will destroy any one that ever calls you the F word. You have the SEXIIIESTTTT curvyyyy body! I LOVE IT! #werkthosecurves.” Miley Tweeted in defense of the singer.

Demi has gained about 30 pounds since coming out of rehab in January and says she looks and feels better than ever. She was radiant on the red carpet at the recent Latin Grammy Awards.

Lovato tweeted backing thanking the former Hannah Montana star and Disney colleague for the kind words.

“@MileyCyrus god I love you. SO DO YOU!!! And whoever called you that has it coming. Miss you more than ever.”

But Miley didn’t stop there.

She was back on Twitter over the weekend telling her 3 million followers that real women have curves and is glad she’s finally getting them.

“@DukeofEarles SO hot! I don’t wanna be shaped like a girl I LOVE being shaped like a WOMAN,” she tweeted. “Trust me ladies your man wont mind either. ;)”

She certainly has a big fan in boyfriend Liam Hemsworth, who says he loves to watch Miley eat, especially juicy steak sandwiches with sauce running down her chin at their favorite restaurant in Nashville.

Miley who’s never been shy about dressing in scanty clothing while out and about, was spotted last week in a stunning red waistcoat and black, low-cut top that showed off her new-found cleavage.

Although Cyrus was criticized when she was younger for not leaving a bit more to the imagination, she’s on the right side of this issue, urging fans to avoid the pressures of being too thin.
