The `Part of Me` singer - who was raised by strict Christian parents and went to a religious school - admits she was disciplined by her teachers after acting out a love scene with a tree. She said: "When I was in sixth grade I was suspended from school for humping a tree! We were doing a play on Greek mythology and I was Aphrodite My love interest was absent and so I used the tree as my partner." "It was a Christian school!" Katy has endured a tough six months following the breakdown of her marriage to Russell Brand but she recently said she thinks the split has given her a "second chance at life". The `Wide Awake` hitmaker - whose 14-month marriage to the comedian ended in December 2011 - says she`s had a new lease of life since they parted ways and has no regrets about the past. She said: "I am totally cool, yeah. I`m just excited. I do have a second chance at life and, also, I already have a brilliant life and I sometimes need to just remind myself. "Everything is a lesson learned. Everybody asks me if there are any regrets: no, this is a very valuable lesson. You have to live life in order to achieve those lessons. It was important to me to show the real honest side of me (in the film)."
