Kim Kardashian and estranged husband Kanye West are privately working on their relationship – after she appeared at his Donda show in a wedding gown

Kim Kardashian and estranged husband Kanye West could be rekindling their romance, sources say.

According to a report by TMZ on Saturday, insiders close to the former couple have claimed they are ‘working on rebuilding the foundation of the relationship’ privately.

On Thursday, Kim, 40, made a statement when she appeared on stage at the 44-year-old rapper’s Donda listening event in Chicago in a wedding gown and veil.

The former couple share four children – daughter North, eight, son Saint, five, daughter Chicago, three, and son Psalm, two.

MailOnline has reached out to Kim and Kanye’s representatives for comment.

The billionaire wore a Balenciaga couture dress while walking out onto the stage at Soldier Field in Chicago for the final song of the show, No Child Left Behind, which caused a frenzy at the stadium.

Kim stole the show as she appeared alongside Kanye and paid tribute to their seven-year marriage, despite the SKIMS founder filing for divorce in February.

At one point, Kanye was seen beaming at her as he appeared to clutch onto a bible.

Kim’s sisters Khloé Kardashian and Kylie Jenner were quick to gush over the moment on social media.

‘Insanely beautiful!!!’ Khloe tweeted with two crown emojis, while Kylie shared close up snaps to her Instagram Story.

As with the last two Donda listening events at the Mercedes-Benz Stadium in Atlanta, Kim brought all four of the couple’s children along for the event.

The beauty mogul also took to Instagram on Saturday to share pH๏τos from the listening event, including ones of her in the bespoke Balenciaga wedding gown.

She simply captioned the posts ‘DONDA’ and ‘BALENCIAGA HAUTE COUTURE’, voicing her support for her estranged husband.

Kim and Kanye wed at the Forte di Belvedere in Florence in 2014, where Kim donned a fitted gown with delicate white lace, custom-made by Givenchy Haute Couture.

A source confirmed to DailyMail.com in February that Kim has filed for divorce. ‘The split is amicable and there is no drama,’ the insider shared at the time.

Kim is asking for joint legal and physical custody of their four young children. It was claimed that neither will contest their prenup.
