(CNN) -- Irish singer Sinead O'Connor's open letter to Miley Cyrus in which she urged the 20-year-old not to allow herself "to be pimped" by the music industry certainly got our attention. It seems to have gotten Cyrus' attention, as well, because the former Disney star, who has dominated the headlines recently following her controversial awards show twerking and nude performance in a music video, took to Twitter to respond. In a tweet, she compared O'Connor to troubled star Amanda Bynes, and she included a Twitter feed of O'Connor's from the past when she wrote about struggling with and seeking help for mental health issues.
