"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!" Duff, 29, added on her blog.

The happy news comes only three months after Duff's younger sister Hilary announced her split from husband Mike Comrie. But the singer is nothing but happy for her sister, sharing her congratulations on Twitter shortly after Duff's announcement. "So happy to not have to keep this news in!!" Hilary wrote, before adding, "Love you guys so much!!!!"
