Shortly after, however, Duff returned to Instagram, seemingly unsure if Momo was the tiny black canine's forever name.
"Guys. My mom needs help. Should it be Momo? should it be Bean? Momo or Bean?" the 29-year-old actress captioned the pic. "Hello! name me please! Woof (that's thanks in dog) and goodnight @loveleorescue #nameme."
Personally, we're partial to the dog's original name from the shelter -- Mojito!
"Another win for #blackdogs everywhere. Mojito has found his forever home... happy in the arms of @hilaryduff," the shelter wrote on Instagram on Monday. "This Little #chug went from 'unwanted' -- to the best life ever. Thank you @hilaryduff for spreading the #adoptdontshop message and welcoming Mojito into your family."
