London: Singer Meghan Trainor says her biggest dream is to start an acting career. The “All about that bass” hitmaker shared her views on acting career in an interview to Star magazine, reports femalefirst.co.uk. She said: "My biggest dream right now is to start an acting career. I'm going to get an acting coach soon." Trainor has already got her foot on the ladder as she was asked to pen new tracks for “The Peanuts Movie”. She added: "I was terrified and honoured (when I was asked to write the songs). When I told my grandmother, she was pumped! I still have to pinch myself. It's unbelievable." The 22-year-old singer was overcome with emotion when she heard her song play in the cinema for the first time but she managed to keep her excitement contained until she left the venue. She said: "I was with my family and when I realised my song was coming up, my heart was pounding out of my chest. When it finally happened, I wanted to stand up and dance, but I kept my cool. My brothers and I were dancing in our seats. It was very emotional. I cried when I walked out of the theatre."
