Lady Gaga has reverted back to Lilly Allen when she praised the singer about her musical risk taking with her latest album 'ARTPOP'.
The 'Poker Face' singer told Radio 1's Scott Mills that Allen was very sweet and she has always been a very huge fan of Allen.
She appreciated Allen that she stood up for artists especially her in particular, and that was really admirable for her to do that, the Mirror reported.
Gaga added that the 'Air Balloon' singer was lovely.
