Hilary Duff expecting a baby girl with boyfriend Matthew Koma

Singer-actor Hilary Duff and boyfriend Matthew Koma are expecting their first child together, a daughter.

Duff shared the news on Instgaram.

"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.
