It seemed as if Hilary Duff and Mike Comrie had the most cordial spilt in celebrity history.
But Britney Spears and her ex-husband Kevin Federline may have beaten them to the title after they reunited at their sons' soccer match in Calabasas on Sunday.
Not only were Britney and her new beau David Lucado seen chatting to the former Mr Spears, but the 32-year-old also took time out to sit and chat to Kevin's new wife Victoria.
Flashing toned legs in black shorts and a tight green T-shirt baring a golden eagle, the Ooh La La singer sat on the grass alongisde 31-year-old Victoria Prince.
Victoria, who is heavily pregnant with K Fed's sixth child, looked equally casual in a turquoise top and ripped jeans.
Reportedly due to give birth this month, the former volleyball player wore her blonde hair up in a messy bun, while Britney hid hers under a baseball cap.
Britney and her 'Everyday Dave' chatted to Kevin as the group queued at an ice cream and lemonade stand.
The former dancer was looking fit after a long battle with his weight, but covered up in over-sized basketball shorts and a matching grey T-shirt.
In a touching display of family unity, it appeared that Britney had won another fan in the form of Kevin and Victoria's daughter Jordan Kay.
Dressed in a pink T-shirt and patterned shorts, the two-year-old seemed to follow the Las Vegas star everywhere she went.
Britney even entertained the little one by showing her photographs she'd taken of Jordan's big brothers Sean and Jayden.
Seven-year-old Jayden joined his mother for a tender time out after taking a tumble on the field.
But the little boy soon bounced back after receiving a hug from his mother and a refreshing drink.
Britney is currently appearing in her Piece Of Me residency at Planet Hollywood in Las Vegas, from which she is reportedly earning a staggering $30million over two years.
