It seems like there is no bad blood between friendly exes Jennifer Aniston and John Mayer, and she still laughs at his jokes.

According to Fox News, during a recent episode of his 'Current Mood' series on Instagram Live, the 42-year-old singer made a joke about having very few "useful" things to say. When discussing late singer Bill Withers, Mayer said: " Whether he was speaking to you or speaking to an interviewer 15 years ago, 14, 13 years ago, everything he said is useful. Four per cent of the things that I say are useful. One hundred per cent of the things he said were useful."
