Kim Kardashian sported matching blonde hair with her son Saint, eight, as they arrived at his basketball game in the Los Angeles suburbs this week.

The 43-year-old adopted her new icy locks at the end of last month, in advance of her showstopping appearance at this week’s Met Gala.

She let her luxurious hairdo tumble freely over her shoulders as she escorted her elder son into the building where his game would be played.

Saint is one of the four children Kim shares with her third ex-husband Kanye West, the others being North, 10, Chicago, six, and Psalm, five.

Kanye was also in attendance for Saint’s game on Friday, but he arrived separately and was seen quickly sneaking into the event.

Kim swung by in a sleek set of black workout gear that allowed her to show off her impressively sculpted midriff as she pounded the pavement.

Warding off the chill in a black jacket, she rounded off the ensemble with a pair or matching butterfly shades and sneakers.

Kanye, by sharp contrast to his ex-wife, was dressed in a head-to-toe white getup including a hoodie and a set of cargo trousers.

The rap star turned up to his son’s basketball game in a gleaming Tesla Cybertruck, pulled up by the hedges and slipped straight out of the car and into the building.

Saint appears to have gone blond in December, as he was first seen with flaxen hair that month while sitting beside his mother at a Lakers game.

Meanwhile Kim acquired her latest hair color last week with the help of hairdresser Chris Appleton, whose other clients include Jennifer Lopez and Ariana Grande.

She proudly displayed the new look this Monday at the Met Gala, which she attended in a head-turning custom ensemble designed by John Galliano for Maison Margiela.

The sleek silver gown featured a dizzyingly tight corset, with a casual grey cardigan wrapped over the top as an artful clash with the frock’s high-octane glamour.

Her outfit ignited a furious debate about body image online, with Megyn Kelly fuming: ‘That is not a healthy image to be projecting to American girls.’

Kim herself confessed that breathing in the corset was ‘an art form,’ in a behind-the-scenes video of her Met Gala preparations for Vogue.

However she gushed that the cinched-in costume piece ‘makes my boobs look so good, and my waist,’ adding: ‘I’ll feel so snatched I won’t even be able to communicate to you how snatched I feel.’

With its floral print, the look paid homage to JG Ballard’s story The Garden Of Time, which inspired this year’s Met Gala theme Sleeping Beauties: Reawakening Fashion.

Kim’s latest sighting comes one day after she fired up her Instagram page to wish her youngest child Psalm a happy fifth birthday.

‘My baby! My sweet, smart, silly, independent baby boy turns 5 years old today! I can’t tell you how blessed I feel to be your mom!’ she gushed.

‘Your calm energy is much appreciated in our house hold lol,’ added Kim. ‘You prove you can be the hulk, spider man or an archeologist any day of the week!’

The reality TV superstar continued: ‘I’ve never met someone who sleeps more than you do and one day I will show you the entire photo album I’ve made of your sleeps! I love you so much always and forever.’
