Wedding bells are ringing for Hillary Duff!
"He asked me to be his wife," the actress announced in a photo alongside her fiance Matthew Koma.
Duff showed off the engagement ring in two side by side photos on Thursday morning. The first image shows Duff smiling into the camera, followed by a black-and-white shot where the newly-engaged couple shared a kiss -- with her left hand in the air.
Koma posted the same photos with the caption "I asked my best friend to marry me."
"Thanks for the promotion babe," Duff responded in the comments with a cute quip.
The "Younger" actress was formerly married to former National Hockey League (NHL) star Mike Comrie, with whom she has a son, Luca.
