Over the weekend, the ‘Come Clean’ singer took to Instagram to share her excitement to be expecting a ”little princess”. Then she shared a photo of herself and Matthew sharing a kiss while her maxi dress showed off her growing baby bump.

She writes:

Guess what guys! @matthewkoma and I made a little princess of our own and we couldn’t be more excited!!!!!!(sic)

Matthew, 31, posted the same photo writing:

We made a baby girl! She will be as beautiful and sweet as her mother … @hilaryduff another incredible chapter begins.(sic)

Hilary and Matthew started dating in 2016 but had some ups and downs and split twice before she confirmed in December they had got back together and were hoping that ”third time’s a charm”.

She said of their relationship:

It’s going so great… It’s the third time that we’ve dated. Timing is such a big deal… third time’s a charm! I think that you have history and a past with someone and love, and just because it doesn’t work out the first time, the second time, as long as there’s not too much damage done, then, it can always work out again.

Congrats to you both.
