"Guess what guys! @matthewkoma and I made a little princess of our own and we couldn't be more excited!" she captioned a photo of herself and Koma sharing a kiss, while the mom-to-be wears a long maxi dress that shows off a hint of a baby bump.
Koma, 31, shared the same picture and captioned it, "We made a baby girl! She will be as beautiful and sweet as her mother @hilaryduff another incredible chapter begins."
Hilary, 30, confirmed she and Koma were back together in December last year, after the duo dated for a few months before breaking things off in March.
