London: Actress Keira Knightley says she is surprised that she is married to musician James Righton even after taking "stressful" guitar lessons from him.
The "Begin Again" actress, who plays aspiring singer Greta in the comedy-drama, says she almost fell out with Righton.
Speaking on the "Today" show, she said: "He is a musician and he did try (to teach me guitar). It didn`t go so well, it`s a miracle we`re still married. I didn`t have the natural ability for the guitar.
"It was a little bit stressful but we`re still together, so it was fine, and I didn`t kill him and he didn`t kill me, so it was fine."
