But the stakes are high in the game of VIP couple friends, and they're only growing with the reported tour collaboration of Justin Timberlake and Jay-Z.
Gwyneth Paltrow and Chris Martin owned Jay and Bey's playtime in 2012. The families celebrated milestones like Gwyneth's 40th birthday in New York and stops on Jay's "Watch The Throne" tour in Europe together.
Yet the mid-year advent of Kim Kardashian and Kanye West, Jay's "Throne" tourmate, distracted the music monarchs from the Goop author. It also provided photo ops of a new foursome at outings like the BET Awards.
Complicating the two-way-tie: rumors of Jay and Timberlake booking a national stadium tour to promote the release of Timberlake's "The 20/20 Experience."
This would thrust Timberlake and wife Jessica Biel directly into the power couple's social diary, making room for a lot more supporting cast members on Beyonce's Instagram.
It'll surely be exciting to see Jay and JT strut their "Suit & Tie" across the country, but who gets the vacation requests, Sunday brunches, and holiday dinner invites? May the best couple win.
