GaGa, 29, is currently working on her fifth solo album, which she has been referring to as “L5”.

The record will be a follow-up to 2013’s “ARTPOP” and GaGa is expected to reunite with RedOne, who was behind her most iconic hits like “Poker Face” and “Just Dance”.

Apart from “L5”, the Mother Monster is readying another joint jazz album with her “Cheek to Cheek” collaborator Tony Bennett.
