She just gave birth to her first child in March.

But former Playmate Holly Madison has been shedding the pounds in no time.

And though she's not as taut as her bunny days, the bubbly blonde is fully confident with her post-baby body, recently revealing her 30lb weight loss in a tiny green two-piece as she soaked up the sun at her pool in Las Vegas, Nevada.

Proving her self-assurance, the 33-year-old model smiled as she stepped out in a turtle-printed string bikini that was tiny on the top.

In fact Holly almost came in danger of exposing herself due to the small fit of the bikini.

The mother-of-one - to daughter Rainbow - was perfectly primped for her patio appearance, sporting a full face of make-up and freshly styled blonde blocks.

Before making a complete exit, she posed for a photo op in her doorway, also wearing a pair of pink-and-white cork-heeled sandals.

After kicking her shoes off, she seductively strolled to her pool.

Preparing for a swim, the fiancee of Paquale Rotella casually dipped her feet in her private pool, warming up to the water.

Holly has already shed at least 30lbs since giving birth almost four months ago and is trying to lose more with the help of a compression belt device called The Belly Bandit.

The Belly Bandit, which costs between $50 and $80, promises to help women get rid of their 'mommy tummy' and is designed to be worn for six to eight weeks after delivery.

Since welcoming her daughter, the TV personality also announced her official engagement to Pasquale last month.

'I know we have a set date already but I officially asked this morning. She said yes!!' Pasquale told his Instagram followers along with a snap for the two.

Holly gushed, 'Thank you pasqualerotella for the most special night of my life! I can't wait to be your wife' via Twitter, explaining that her man proposed to her officially on a Ferris Wheel in Las Vegas.

In case people didn't hear her the first time, she again tweeted: 'I'm officially engaged!!!' and posted a happy snap of herself at the carnival.
