Haylie Duff’s boyfriend Matt Rosenberg broke the April Fools’ Day tradition by doing something sweet instead of something mischievous: he proposed to her.

Duff used Instagram and her food blog to share the news with the world.

In her official engagement announcement, on her Real Girl’s Kitchen blog, she stated, “This week has seriously just become the best week of my life! As if announcing The Real Girl’s Kitchen tv show wasn’t enough, Matt just took me by total surprise and proposed…on April Fool’s Day of all days! The moment was genuine and sweet (like him!) and I couldn’t wait to say yes!”  She then added, “We are so excited and happy to share our wonderful news with everyone! We both feel so blessed to have the love and support of our family and friends and can’t wait to start this new adventure!”

On Instagram, Duff posted a picture of the happy couple with the caption “The future Mrs. Rosenberg #Love @mr_sts.” Rosenberg also posted a picture with the caption, “She said yes!”

People immediately congratulated the couple on the Instagram pictures, comments on Real Girl’s Kitchen blog, and tweets to the couple. However, one special congrats came to Duff via her sister Hilary.

Hilary sent out a couple tweets expressing her happiness for her sister’s engagement news.

The news of Haylie’s engagement comes three months after Hilary announced her separation from husband Mike Comrie.

Congrats to the happy couple. May the day of fools bring them luck and happiness for years to come.
