Even with appearances on Lizzie McGuire and That's So Raven, Hilary Duff's older sister, Haylie Duff, has kept her private life further away from the public than her younger sis.

In April 2014, Haylie Duff became engaged to her boyfriend of two years, entrepreneur Matt Rosenberg, who owns the T-shirt company Subway Tile Shirts, according to Time. "The moment was genuine and sweet (like him!) and I couldn't wait to say yes!" Duff wrote on her food blog, The Real Girl's Kitchen.

However, before any wedding bells began to ring, the former Disney star became pregnant with their first daughter, Ryan. "We talk about it and think, 'Maybe now we're ready to do it' and then life happens and toddler happens," Duff told People in 2018, as the as the couple was awaiting the arrival of their second daughter, LuLu. "Maybe after the craziness of a new baby dies down we'll be ready to talk about it again," Duff said. 

As of December 2019, the two have yet to tie the knot. "We feel married already," she noted to People.
