It's hard to imagine the sexy "Transformers" star setting foot in Walmart, and maybe this is why: According to the National Enquirer, Megan was banned from a local branch of the discount department store in her hometown in Florida after she was caught stealing a $7 tube of lip gloss. "Megan was quite a rebel growing up. She thought she could get away with anything, and definitely had sticky fingers," a friend reportedly told the gossip rag. "She would pocket things like candy and gum from convenience stores." We're pretty sure Megan doesn't have to steal beauty products now!
