Auntie Hilary! On Thursday, Sept. 24, Hilary Duff took to Instagram to share a precious photo of her tiny niece, Ryan Eva, the daughter of the Younger star’s older sister, Haylie Duff and her husband, Matt Rosenberg

“you put a spell on me my beautiful baby niece #ryanavaerhard @haylieduff @mattyrose3 baby boss,” Hilary, 27, captioned the close-up photo of the blue-eyed baby girl. 

Haylie, 30, welcomed her first child back in May. She was already aunt to Hilary’s son, 3-year-old Luca, whom she had with her ex Mike Comrie.

“So many people have asked me, ‘What kind of advice has Hilary given you along the way?’ And she really hasn’t,” Haylie told Yahoo Celebrity recently. “She’s just been there for me. She hasn’t tried to push her way on me. There have been times where I’ve been physically overwhelmed, and she’ll just come over and hold the baby for an hour. Just physically being there has been the best thing she’s done for me in this process.”
