Hilary Duff has fallen in puppy love.

The 28-year-old actress was "shattered in a million pieces" when her French bulldog, Beau, died earlier this year, but she has welcomed a new puppy into her household. And this little Frenchie's face might look familiar -- she's Beau's sister!

"I'm peaches.... I am Beau's sister and new trouble maker at the Duff house!" Hilary captioned an adorable Instagram of Peaches.

"I have a chunky little butt (it is the year of the booty riiiight?) and I hop like a bunny to get to and fro!" she added. "I give lots of kisses and like to try to rip all the fur off of my new big brother Dubois tail! He doesn't like it.... Or me... yet..... But he willlllll!"

Beau, who the Younger star adopted in 2014, went to "doggy heaven" in January. At the time, Hilary wrote, "I can't fathom never holding his heavy little head in my hands with his two big eyes looking at me again. Remember every day to be grateful for what we have that makes our hearts happy and full."

She first met Peaches last week and said, "I think she's asking to come home wif me."

We know how that turned out. And now we can anticipate plenty more sweet shots of the new pup. Like this one of a hilariously guilty-looking Peaches, with the caption, "I didn't do it."
