The Naughty or Nice star is pregnant, announcing her baby news on Instagram and her blog Tuesday.
"Happiest girl in the world! Finally can let everyone know that Matty @mr_sts and I are expecting! #BabysFirstJordans," Hilary Duff's older sis captioned a shot of mini pink and black Jordans on Instagram.
Then, she headed to her blog to tell fans the sex of the baby (if they couldn't tell by the shoe colors), writing, "I have always shared everything with ya'll here on Real Girl's Kitchen...You have been with me through dating, falling in love, getting engaged and now the moment that has changed my life forever!"
"Today we have big, exciting, wonderful, magical, amazing news!," she continued. "Matty and I are expecting a baby girl! Entering this new chapter of our lives and our relationship has been so special. We are so happy and so in love with her already!!!"
This is the first child for Haylie and her fiancé Matt Rosenberg, who announced their engagement in April on Instagram with a snap of the 29-year-old starlet showing off a diamond sparkler on her ring finger.
"This week has seriously just become the best week of my life!" Haylie later wrote on her Real Girl's Kitchen blog. "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! We are so excited and happy to share our wonderful news with everyone!" she continued. "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!"
Congrats to the couple!
