Michael Phelps  is officially one proud dad! The Olympic swimmer took to Instagram to introduce his first child  to the world (of social media!) with a sweet snapshot. In the heartwarming black-and-white pic, the shirtless  dad is cradling his newborn as his fiancée, Nicole Johnson, lovingly looks on. "Welcome Boomer Robert Phelps into the world!!! Born 5-5-2016 at 7:21 pm !!! Healthy and happy!!!" the 18-time Olympic gold medalist wrote . "Best feeling I have ever felt in my life!!! @nicole.m.johnson and Boomer both healthy!!! #boomerphelps 📷 @boonestudios."
While this baby'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 like Kim Kardashian  are releasing their own photos — either on their own or through photo agencies — to bypass the whole magazine scenario. See how your favorite celebrity parents debuted their little ones, and tell us how you think the newest babies will be introduced to us!
