For a long time running, it seemed People had a monopoly on introductory celebaby photos. Nicole Richie, Christina Aguilera, Jennifer Lopez, and the Jolie-Pitts all turned to the well-established magazine to show off their newest family members. However, today, many celebs are turning to competitors who are doling out generous offerings to new parents. Others are releasing their own photos — either on their own or through photo agencies — to bypass the whole magazine scenario.

Happy Mother's Day to all the mothers out there, it can be a hard job but the best! Good work!"

Fresh off her festival getaway, Hilary has jumped onto promotional duties for the latest and final installment of her Elixir trilogy, True. On Tuesday, she signed hardcover copies of her fictional love story, which was officially released the same day, at a local book shop in La Verne, CA. The multitalented star took to Twitter to share her gratitude: "Great night...Thank you to all my loyal and devoted fans. You guys mean so much to me!"
