US reality star Lauren shared a picture of her pet on Instagram yesterday and it shows the doggy curled up on a blanket.
Alongside the picture, Lauren told her followers: "Newest member of the Conrad clan stole me heart."
Fashionista Lauren - who got engaged to boyfriend William Tell last October - already has two dogs, Chloe and Fitzgerald, but she hasn't yet revealed the name of her latest pooch.
She's definitely got her hands full, as a fortnight ago Lauren shared a funny video of Fitzgerald - or Fitz for short - laying on his back after chewing one of her shoes.
Lauren can be heard saying: "Did you do this, Fitz? Did you do this? Fitzgerald?"
But even though Lauren is telling him off in the clip, Fitz can't help but wag his tail. Too cute!
