After months of fat jokes, Lisa Marie Presley has given birth to twin girls. While the names were not released, the girls, who were delivered via C-section Tuesday, came in at 5 pounds, 15 ounces and 5 pounds, 2 ounces. Presley's publicist said the "babies and mom are happy and healthy and resting at home." Elvis Presley's only daughter is married to music producer Michael Lockwood and has two teenagers from a previous marriage. (More Lisa Marie Presley stories.)
