HAILEY Bieber has given fans a flash of her flat stomach just two months after giving birth to her baby son.

The model, 27, was spotted as she headed to the gym while wearing a cropped black zip-up hoodie and black stretchy pants.

Hailey had slicked back her brunette hair into a bun and hid behind a pair of black sunglasses as she made her way inside.

The new mom was believed to be going to a pilates class in Beverly Hills for the second day in a row.

On Tuesday, Hailey proved her dedication to getting in shape by leaving another class looking fresh-faced.

For that session, she opted to wear a tight pair of cycle shorts and another crop top, adding a green jacket for extra warmth.

WELCOMING JACK

Hailey and her husband, Justin Bieber, announced the birth of their first child – a son called Jack Blues – on August 23.

After becoming a mom, Hailey took a step back from the spotlight and social media.

However, as these new gym pictures show, she is slowly making her way back into the public sphere.

Earlier this month, Hailey even posed for a belly-baring selfie at home while wearing a massive diamond necklace in honor of her baby.

Justin, 30, shared the first photo of Jack after he was born.

In the shot, Hailey was holding onto their baby son’s foot, which was wrapped in a white blanket.

“WELCOME HOME,” Justin, who married Hailey in September 2018, wrote. “JACK BLUES BIEBER.”

Hailey simply added “Jack Blues” with a beat and blue heart emoji on her Story.

It is no surprise Hailey has been keen to get back in shape following the birth of her son.

Before getting pregnant, the model was a regular at Pilates.

Speaking on the Women’s Health Going For Goal podcast, Hailey explained why it was her favorite way to exercise.

She said, “I used to be a ballet dancer so pilates for me gets my body personally in the best shape because it’s very elongating.

“A lot of the movements in pilates are very similar to dance.”

Hailey had also previously told how she particularly favored hot pilates.

The high-intensity, low-impact class combines a very hot studio with traditional pilates techniques.

In another chat with Vogue Australia, she revealed, “I’ve been doing hot pilates for years now.

“I find that when you do any hot class your muscles are more pliable and you’re stretched out easier.

“You come out dripping in sweat and my face is like a tomato and it’s good for your skin! I love it! I’m obsessed and it’s addictive.”

Hailey and Justin announced they were expecting in May this year.

Just a few days after Jack’s birth, pop star Justin attended a Churchdome service and became emotional.

One of the readings said, “We love Jesus, through the love of children.”
