Phelps Family Celebrates Boomer's First Birthday With The Cutest Shark Cake

It looks like Boomer, the son of Olympic swimmer Michael Phelps, is taking after his father's affinity for water with a "shark attack" themed party to celebrate his first birthday.

Phelps posted a picture on Instagram of the family along with Boomer's amazing shark-shaped birthday cake. According to the caption, the cake was made by Heartsweet Cakes, a bakery based in Phoenix, Arizona.

"It was an absolute pleasure to design and create this birthday cake for @boomerrphelps 1st 'Shark Attack' birthday," Heartsweet Cakes wrote in the caption of an Insatgram post. "Thank you @m_phelps00 and @mrs.nicolephelps for asking me to make his cake. Watching him "attack" his smash cake was my favorite part of it all! There is nothing more rewarding to me than creating a couple's wedding cake and following it up with other cakes to celebrate special life moments in a family, so I am truly humbled and honored to have been a small part of Boomer's 1st birthday!"
