What baby weight? Holly Madison shows off her stunning post-pregnancy figure in a bikini just SIX weeks after giving birth

During her pregnancy, Holly Madison stuck to a plant-focused diet and regular exercise.

And on Saturday in Las Vegas, a mere six weeks after giving birth to daughter Rainbow, the television personality showed that a little dedication goes along way.

At the opening of TAO Beach at the Venetian Hotel, the 33-year-old stripped down to just her bikini - and wowed everyone around her.

Wowza! Holly Madison may have had a baby just six weeks ago, but she showed a stunning figure at TAO Beach in Las Vegas on Saturday

The bikini babe displayed a toned tummy any woman would envy.

A blue and turquoise string bikini covered the new mother's famous curves but let the rest of her figure shine in the sun.

Her thin arms and fit legs had remained the same size throughout her nine months with child, with only her belly ever growing.

But thanks to a healthy diet, her trim tummy appeared to have returned to its normal svelte size within mere weeks.

Her quickly shrinking waist may also be due to a trick that fellow mother Jessica Alba also recently admitted to using - a corset.

The former Peepshow star posted to her Celebuzz blog back in March a photo of two corsets.

'I got myself some waist cinchers to help get my figure back after pregnancy,' she said.

'I'll let you know how they work!'

Bye, bye, baby weight! The E! star gained 40lbs throughout her pregnancy and has lost 30lbs of it so far

Her beach babe display on Saturday spoke for itself, as the fiance of Pasquale Rotella appeared to be in phenomenal shape.

One would never guess that she gained 40lbs during her pregnancy, but the E! star opened up to In Touch about the gain.

She said that she still has 10lbs to lose, but isn't in any rush.

'Who cares if I still need to lose 10 pounds?' she shared. 'I've been really healthy and done the best I could. I'm really proud of how I look right now!'
