Swedish House Mafia will reunite and tour together in 2017, multiple sources close to the situation tell Billboard, although the group's longtime manager Amy Thomson categorically denied to Billboard and via Twitter that a reunion is in the works. 

The sources indicated that performances are likely to include Miami's Ultra Music Festival (where SHM members Axwell & Ingrosso are already billed as headliners), as well as New York and Los Angeles stops. 

However, "There's no reunion of Swedish House Mafia planned at all," Thomson tells Billboard. " Even if there was, it's ridiculously private.  They're not playing at Ultra.  There's no reunion tour planned." 

The sources maintained that the reunion is on. 

A reunion would make sense for all parties involved.  While Swedish House Mafia sold out global arena tours and released a top 10 single in "Don't You Worry Child," none of its members have returned to the Hot 100 since the split.  Group members Steve Angello, Axwell, and Sebastian Ingrosso have not performed together since their One Last Tour finale at Ultra Music Festival on March 24, 2013. 

Axwell & Ingrosso returned to Thomson's fold this year after departing briefly to join Ash Pournouri's At Night Management in 2015.  The duo have mostly played marquee festivals outside Europe, and a planned album release on Def Jam Recordings has yet to materialize.  Angello is represented by Scooter Braun Projects for management. 

Rumors of a Swedish House Mafia reunion surfaced in July following a post by YouTube curator Proximity, but were quickly shot down by the artists. 

"At this point we're not planning on reuniting and we have really no further comments on what the future for SHM looks like," Axwell & Ingrosso told Billboard in a July statement. 

Speculation flared up again in October after purported screenshots of a deleted Axwell tweet hinting at a Swedish House Mafia reunion began circulating on the web.  However, Axwell took to Twitter to claim the image was a fake.
