Hailey Bieber showed off her new hair color on Saturday.

The 27-year-old model debuted her ‘lighter’ blonde locks in a stunning snap posted to her Instagram Story, just weeks after welcoming son Jack Blues with her husband, Justin Bieber, 30.

In the snap, the Arizona native posed bare-faced as she showed off her golden hair that appeared to be significantly lighter than the chocolate brown color she previously sported.

She wore a chic pair of reading classes and her diamond ‘B’ necklace as she posed slightly puckering her lips.

‘Lighter for the fall,’ she penned, alongside a blonde haircut emoji.

Though the wife of the Holy hitmaker has not posted as frequently since late July, her locks look drastically different ahead of the autumn season.

Hailey was previously blonde in 2015 and 2018 leading up to her nuptials with Justin.

The pair tied the knot through the courts back in September 2018 after almost four years of dating on and off.

They were first introduced in 2011 by Hailey’s father Stephen at the premiere of Justin’s documentary Never Say Never.

Back in May, Justin and Hailey announced they were expecting as they shared snaps of the new New York native flashing her 𝑏𝑎𝑏𝑦 bump.

Hailey gave 𝐛𝐢𝐫𝐭𝐡 sometime in late August sharing a glimpse of her 𝑏𝑎𝑏𝑦’s tiny foot. Neither she or the Baby singer have confirmed their son’s date of 𝐛𝐢𝐫𝐭𝐡.

Just days later, a source close to the new parents told PEOPLE that Justin was ‘already a great dad.’

‘The 𝑏𝑎𝑏𝑦 is such a miracle. He’s adorable and doing well. Hailey’s doing well too,’ the source said at the time.

And being parents is something the A-list couple had dreamed of for years.

‘The pregnancy was something that they very much wished and prayed for. The day they found out that Hailey was pregnant, was the best ever for Justin,’ the source added.

‘Justin was over the moon with excitement. It was a big celebration for them,’ the source revealed of Jack Blues’ 𝐛𝐢𝐫𝐭𝐡.

The ‘JB’ initials read along the lines of tradition for the Bieber clan starting off with Justin’s dad, Jeremy Jack Bieber, the Holy singer himself and his youngest siblings Jaxon and Jazmyn Bieber.

The new parents have yet to confirm that their son’s name is a nod to Justin’s dad’s middle name.
