Is Michael Phelps' Son Hollywood's Most Popular Baby? Every Celebrity Who Has Met Boomer Phelps

At less than five months old, this growing boy has already met a few important people

Wherever Boomer Phelps goes, Hollywood may just follow.

Ever since Michael Phelps and fiancé Nicole Michele Johnson welcomed their son in May, fans of the couple haven't been able to get enough of the baby boy.

Yes, we loved his appearances at Michael's Olympic races during the 2016 Rio Games. And you better believe we're following the four-month-old on Instagram each and every day.

But as the family of three headed to Milan for a little fall getaway this weekend, some may have thought it would be the perfect opportunity to get away from it all and not be recognized every moment. For better or worse, that's not exactly how things are going.

In between sightseeing and snapping selfies, Michael and Nicole were able to find some friends in Milan. And sure enough, these BFFs named supermodel Taylor Hill and actor Michael Stephen Shank couldn't get enough of the youngest visitor.

"Sooo I guess I love to flirt," Boomer's Instagram read Sunday night. "I wonder how I did? @taylor_hill."

Nicole added, "#cheers to finding friends in #milan."

The famous—and friendly—encounter got us thinking of all the familiar faces Boomer has been able to meet in just a few short months of living. From talk-show hosts to award winning journalists, we're pretty impressed with Boomer's friends and acquaintances.
