Lady Gaga reveals how she got back after 'really losing it for a while'

Lady Gaga has revealed that she got "really lost for a while" and felt like she didn't even know who she was anymore until she collaborated with Tony Bennett for latest album 'Cheek to Cheek.'

The 28-year-old singer said that the collaboration taught her a lot, where she found that boxer, that fighter within her who was ready to take on the world, the Independent reported.

The 'Poker Face' singer, who took piano lessons and won inter-school jazz competitions during childhood, will show her passion in 'Cheek to Cheek' and added that she wanted to do something different with the 88-year-old jazz artist from what he'd ever done before, with any other jazz singer.
