Paramore have recruited two new temporary members following the departure of Josh and Zac Farro in December.
Justin York, brother of guitarist Taylor, and drummer Josh Freese will join the Tennessee rockers for their upcoming tour of South America.
The dates begin in Brazil in February.
Josh and Zac Farro left in December 2010 with Josh blogging they were treated as "less important" than singer Hayley Williams.
Writing on her Twitter page Williams said she'd already begun working on demo recordings for the band's new album, the follow-up to 2009's Brand New Eyes.
Guitarist Justin York used to play with Tait, whilst Freese has played with bands including A Perfect Circle and The Vandals in the past.
They have not currently joined the band on a permanent basis.
