"You see, last year, when @kevinmanno & I started planning our wedding, we couldn't find any good ringer bearers [sic] or flower girls so we decided to make our own," she wrote next to a pic of her rocking 'Mom Jeans.'

The 31-year-old said in a separate statement to Us Weekly, "We've been pretty vocal about our desire to start a family as soon as possible and feel incredibly lucky to be able to share that we have a little one on the way!"
