The group's producer Mr. DJ has revealed the pair are at Stankonia Studios in Atlanta recording material for their own projects and not an OutKast album, after the duo announced they will reform to play 40 festivals this year.
Mr. DJ told Revolt TV that Andre 3000 is set to release his debut solo album in coming months, while Big Boi is working on his third solo LP, the follow-up to 2012's 'Dangerous Lies and Vicious Rumors'.
The producer suspects the duo, who are kicking off their tour by headlining Coachella in California this April, will reunite after the gigs and plan new material.
He explained: ''I get the feeling that the energy and camaraderie from the tour will bring everything full circle. We may make it back in for an album following that.''
The band's former manager Queen Latifah hinted they were already making an OutKast album but later backtracked on the claim.
Earlier this month she wrote on Twitter: ''PS: the rumor mill says I predicted an @Outkast album...except I didn't. Sorry to get twitter a flutter. XO. (sic)''
OutKast went on hiatus in 2007 and have not performed together since 2004.
This year is the 20th anniversary of the pair's 1994 debut album 'Southernplayalisticadillacmuzik'.
There are currently five separate teams working on 'Game of Thrones' projects at HBO.
She's a big fan of the band and this week she got to perform with them.
