Hailey Bieber shows off her very toned tummy as she poses in a hot pink bikini top

Hailey Bieber has been attending Pilates classes at Forma Pilates in Los Angeles almost daily with her best pal Kendall Jenner.

And on Thursday the 25-year-old model revealed just how stunningly her fit figure has become as she wore a bright pink bikini top by Inamorata for images shared to Instagram.

The Versace model put on a busty display in the triangle top that made the most of her abs as she added light gray sweatpants.

The 5ft7in beauty had her brunette locks clipped in front for a teen spirit look.

She added several beaded necklaces and a few longer gold chains, one with a cross pendant.

The clip was from TikTok, it was noted, but shared by pal Emily Ratajkowski’s Inamorata line.

Inamoratawoman’s Instagram account shared, ‘Queen @haileybieber in the Orpheus Top in Fuchsia Velvet.’ It’s from the Velvet Swim line.

Fans responded with fire and heart emojis.

Earlier this week, Hailey helped her husband Justin Bieber celebrated his 28th birthday with an extravagant pool party at their Beverly Hills mansion.

She took to Instagram on the same day to sing her husband’s praises in a sweet Instagram post shared with her 41.4 million followers.

‘There are a lot of amazing and beautiful things about this life, but the most beautiful part is that I get to live it with you,’ wrote the catwalk star while sharing photos of herself with the Sorry singer. ‘I love you.. here’s to 28 ❤️.’

The couple gazed into each other’s eyes lovingly in a sunset photo snapped in the middle of a field, while they went in for the kiss in a cute black-and-white photobooth-style follow-up.

The two were more playful in other photos, including one in which they gazed at each other again, this time with their tongues extended.

Justin even got close to licking Hailey’s neck in a sunny photo snapped aboard a yacht.

The couple famously first met at one of Justin’s concerts, and they later dated briefly from December of 2015 to January of the following year.

The two gave their relationship a second chance in June of 2018, and they were engaged just a month later.

They later had a secret wedding in November of that year, but they repeated their nuptials for a bigger crowd of friends and family with a South Carolina ceremony in September 2019.
