Final answer:
A typical prepubescent female like Rihanna will likely care more about their appearance and what they wear, and may also start to have romantic feelings for peers, experiencing 'puppy love.'
Step-by-step explanation:
As a typical prepubescent female, Rihanna is likely to start experiencing changes in her interests and behaviors due to the onset of puberty. One common change is that she might care more about her appearance and what she wears. During this stage, girls often become more conscious of their personal style and body image as part of their developing identity.
Another aspect of pubertal development is the potential for Rihanna to start having romantic feelings toward a peer, which can lead to instances of "puppy love." This is a form of early romantic or platonic attachment, which, while not deeply emotional, signifies a stepping stone in social and emotional development.
