Holly Madison gave birth to her baby girl only three months ago.

However the former Peepshow star appears to have sprung back to her pre-pregnancy shape as she took in an energetic morning run in Las Vegas on Saturday.

Holly was sweating off the pounds with a smile as she bounced along the neighbourhood street amidst trees and green foliage.

Great shape: Holly Madison set off for a Saturday morning run in a sporty pink crop top and tiny grey shorts

The 33-year-old showed off her bosomy figure in fuchsia athletic bra and grey shorts with comfy elastic waistband.

Her scanty attire did little cover that hourglass form, exposing plenty of cleavage, stomach and legs.

Adding a fashionable flair were Holly’s turquoise-blue and pink trainers.

She ran alone but had a handy iPod plugged into her ear to keep her entertained and motivated.

The new mother wore her blonde hair pulled back in a ponytail during most of her heart-pumping routine, but during her stretching portion allowed it fall out of its clasp and around her shoulders.

Holly eventually slowed down to extend those muscles in a few relaxing stretches.

Throughout her pregnancy Holly stuck to a healthy diet and exercise regime.

After Rainbow was born, Holly consumed 1,100 calories a day to help shed the excess 40 lbs gained during those nine months of pregnancy.
