Ed Sheeran dropped a huge bombshell last week when he revealed that his latest single Perfect is getting a special remix, which will include new vocals from a guest feature.
"I've got something dropping next Friday," explained Ed at the time. "It's a really f***ing big deal. I'm just basically going to 'Despacito' Perfect."
Ed is alluding to Luis Fonsi and Daddy Yankee's Despacito, which while already popular in Latin territories, was blasted to the top of charts globally following the release of a remix featuring Justin Bieber. Despacito ended up as an 11-week chart topper here in the UK.
Sounds like a recipe for success? It could be perfect, as long as the new featured artist on the duet is a good choice. So who should it be?
Ed has worked with a lot of superstars in his time, whether that be writing music for them, or laying down vocals together. The most recent megastar Ed teamed up with was his good friend Taylor Swift - Ed features on Taylor's Reputation album track End Game. Having previously teamed up for Everything Has Changed from Swift's album Red, could a third collab be their biggest yet?
If we're talking about Despacito, surely we have to throw Justin Bieber's name into the mix? It's not like the two are strangers either - Ed has written two UK Number 1 singles for Justin, Love Yourself, and Cold Water. Biebs is a safe bet in our eyes.
We see potential in fellow Canadian Shawn Mendes too, after he and Ed performed on Shawn's tour earlier this year. They could both be singing to respective love interests on the remix - think Sam Smith and John Legend's Lay Me Down with a festive twist.
Ed talked about this new duet being a "really f***ing big deal", which lends itself to an artist of Beyoncé's magnitude, right? She recently appeared on a surprise remix of J Balvin's Mi Gente, and she dazzled on Eminem's latest single Walk On Water. Having previously sang together at Stevie Wonder's GRAMMY tribute concert, have their paths crossed again?
Looking to other people Ed has paired up with in the past, Jessie Ware, Rita Ora and James Blunt are all possibilities. Ed has penned two songs for Jessie Ware, while he also wrote Rita Ora's comeback single Your Song. James has been supporting Ed on his recent tour dates, so did they find time to get into the studio?
