A veteran of the magazine first-photo right of passage, Christina Aguilera  went a much simpler route to introduce her little girl to the world this weekend — she tweeted a photo of 6-month-old Summer Rain Rutler  with the caption, "Watch out...another one's getting ready to conquer the world! #driven #diva2."
While baby Summer's debut was a low-key one, for a long time running, it seemed People had a monopoly on introductory celebrity baby 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. See how your favorite Tinseltown parents debuted their little ones, and tell us how you think the newest Hollywood babies will be introduced to us!
