Actress Gwyneth Paltrow is taking guitar lessons from husband Chris Martin to prepare herself for her new film. The actress plays an alcoholic country singer in her forthcoming movie “Love Don't Let Me Down” and admits she was “embarrassed” when she asked Martin, the Coldplay frontman, to help her master the instrument, reports femalefirst.co.uk. “He was so helpful, so sweet and encouraging. I mean, it's embarrassing to be playing in front of your husband, especially when he's in one of the world's most successful bands,” said Paltrow.
