Now it appears their friendship is going from strength to strength as they both attended Global Citizen’s Vax Live concert on Sunday.
Jennifer performed two songs at the event, dubbed 'the concert to reunite the world', and as she left the stage, Ben made his entrance just seconds after.

Ben was always scheduled to appear at the concert – which was held to encourage world leaders to make sure COVID-19 vaccines are "accessible for all" – but his swift appearance on stage suggests that he may have been watching and supporting Jennifer from the sidelines.
Last week, the former couple were spotted spending time together in Los Angeles, weeks after the singer's split from Alex.
In pictures posted by Page Six, Ben was snapped exiting Jennifer's white Escalade SUV.
They were not pictured together in the car, but sources told the publication that "security picks him up at a nearby location and drops him off after spending a few hours at her house".

Oscar-winner Ben has reportedly been to see Jennifer several times since she returned to Los Angeles from the Dominican Republic, where she was shooting new film Shotgun Wedding.
Paparazzi pictures showed Ben at the Hotel Bel-Air on 22 April, and hours later Jennifer was picked up from the spot by her white SUV.
On 28 April Ben was pictured heading to Jennifer's home in Bel Air, and a day later on 29 April, the latest pictures were taken showing Ben dropping his car at the Hotel Bel-Air and being collected by the white SUV.
Jennifer and Alex split in April
The same car dropped him back at the hotel hours later. However, the insider insisted they were "just friends" and had always remained close, even years after they ended their engagement.
Ben and Jen were engaged in 2002 and dubbed "Bennifer" by fans. A year later they announced they had postponed their wedding, and in early 2004 confirmed they had split.
Jennifer, 51, split from Alex, 45, in early April. The couple, who had been engaged for two years, released a joint statement confirming the news.
