Duff also posted a peek into Mae's birthday party on her Instagram Story over the weekend.

Mae wore a sparkly pink dress to the event, which was Disney princess-themed. Her accessories included a pink and purple balloon crown with a ballon animal on top of it and unicorn face paint.

The proud mom posted photos on her Instagram Story of the little girl being embraced by her older brother, 12-year-old Luca Cruz — whom Duff shares with her ex-husband Mike Comrie — and posing with her big sister, Banks Violet. Banks, 5, is the Lizzie McGuire star's first child with Koma, 36.

Mae sang with Disney characters Tinkerbell, Merida and Elsa at her party, and blew out candles on a three-tier green, purple and pink cake with her Disney friends by her side.

Duff and Koma announced that they are expecting their third child together (her fourth) via their family holiday card shared on Instagram in December.

"Buckle up Buttercups, we're adding one more to this crazy bunch!" read a message on the back of the card.
