Hilary Duff Celebrates Daughter Mae’s First Birthday With ‘One-Derful’ Rainbow Cake

Hilary Duff is celebrating one year around the sun with her baby girl, Mae. The “How I Met Your Father” star took to Instagram on Thursday to share some sweet snaps from Mae’s first birthday party. In the cute photos, Mae sports a gold party hat with a “1” on it as she eats her festive treat. The toddler also grins while sticking her hands into the frosting, which reads, “Mae Mae is One-derful.” Mae’s big day comes just days after Hilary’s son, Luca, celebrated his 10th birthday.
