Stop calling me! A few weeks back, teen heartthrob Justin Bieber tweeted a phone number minus one digit and asked his 19 million followers to “Call me right now.” Soon after, 81-year-old Dallas great-grandmother Dilcie Fleming began receiving constant calls from girls eager to profess their love. “Justin, I know you are there,” said one message. “I’m sorry I called you so late, but I just got your number.” But the octogenarian is no fan of the Biebs and is considering suing. “I’ve had this number since 1966,” Fleming said.
