He put a ring on it!
Hilary Duff is engaged to her baby daddy, Matthew Koma! The "Younger" star announced the news on Thursday, showing off her gigantic rock.
"He asked me to be his wife," Duff captioned the shots.
In one photo, the duo's smiles show they're clearly ecstatic. In the other, they share a sweet smooch while Duff displays her gorgeous diamond and perfectly manicured nails.
Koma reciprocated Duff's excitement, taking to Instagram and writing, "I asked my best friend to marry me."
Duff and Koma welcomed their first child together -- a daughter named Banks Violet Blair -- in October.
This will be Duff's second wedding. She was previously married to NHL stud Mike Comrie. The two, who got divorced in 2016, share 7-year-old son, Luca.
Congrats to the happy couple!
