But the most exciting of milestone of all? Potting training her new puppy!
The singer’s 12-week-old Maltese, T.K., is still finding his way to the pee pad. Amaro tells PEOPLE, “He’s like, ‘No, I’m going to pee over here on this floor.’”

See Amaro talk about her fluffy new companion in our exclusive PEOPLE interview!
