Kim Kardashian West and Kanye West are friendly exes.

On Thursday, the 40-year-old Keeping Up with the Kardashians alum and her estranged rapper husband, 44, enjoyed a night out with friends at Nobu Malibu. The duo was photographed leaving the celebrity hotspot with Kardashian West’s pal and Chief Marketing Officer of KKW Brands Tracy Romulus.

A source tells PEOPLE that during the dinner, Kardashian West and West “acted more like friends.”

“Kim and Kanye had dinner with a small group of people. It seemed like a business dinner. Kim and Kanye sat next to each other. They acted more like friends. Kanye was in charge of the conversation. Kim was more quiet. Kanye also picked up the check,” the insider adds.

For the evening out, Kardashian West wore a bright purple gloved catsuit, which she accessorized with a long maroon leather coat and a pair of sunglasses.

West, meanwhile, kept it cool in an all-black ensemble, which he paired with a black hat, sunglasses and a silver chain around his neck.
The outing comes after the SKIMS founder filed for divorce from the musician back in February after the pair weathered a tumultuous year together that included West’s unsuccessful presidential bid. They were married for about seven years.

Kardashian West and the “Stronger” rapper started dating in 2012 and tied the knot in May 2014.

Together, the estranged couple share four children — daughters North, 8, and Chicago, 3½, plus sons Saint, 5½, and Psalm, 2.
