Lady Gaga ate David Letterman's questions during an appearance on the host's US chat show on Monday (May 23).
The singer ripped up Letterman's notes and stuffed half in her mouth after becoming frustrated with his questions.
"I'm just so fed up with all of this," she said.
Lady Gaga appeared to grow restless throughout the interview, which saw Letterman ask her whether she had even eaten a Barbie doll head on tour. He also asked her if she liked to relax by fly fishing.
The singer was appearing on the Late Show With David Letterman to promote her new album 'Born This Way', which was released yesterday.
