Little Boomer Phelps may be just over a year old, but dealing with a newbie toddler hasn鈥檛 stopped his parents from expanding their family right away. Twice-married Michael Phelps and Nicole Johnson (along with Boomer, natch) have just announced that baby number two is on the way!

The 32-year-old former Olympian posted messages across all three of the family鈥檚 Instagram accounts, including Boomer鈥檚 (yes, Boomer is already on social media, and a verified account, no less). On Phelps鈥檚 own account, he captioned a pic of his wife and son, who happens to be holding a pregnancy test clenched in his hand, along with the joyful announcement, saying, 鈥淣umber 2 on the way!!!! So excited!!鈥 He added, 鈥淲onder if it鈥檚 a boy or a girl??鈥

32-year-old Johnson (who is a former Miss California USA and now goes by Mrs. Nicole Michele Phelps) posted the same pic to Instagram, but with a shorter yet totally sweet message, saying, 鈥淟il mans going to be a Big Brother!!!鈥 Eee! Look at how happy they are!

As for the soon-to-be big brother, Boomer鈥檚 pic may be the very best, showing the little dude sporting an absolutely heart-melting smile and clapping his hands together as someone holds up the positive pregnancy test in front of him. 鈥淪o excited to see what mama is having!! Do I get to have a brother or a sister?!?,鈥 the caption reads, though by the looks of it, Boomer will be thrilled either way.

Now we鈥檙e just left wondering if the new baby will get a unique name like their big bro. We鈥檙e thinking Zoomer Phelps or Champ Phelps or maybe even Gold-Medal Phelps.

What do you think Michael Phelps and Nicole Johnson should name their second baby? Let us know @BritandCo!
