Superstar Rihanna first shared a video of her son, who was born in May, on the internet on Saturday.
In the 45-second video posted to TikTok, the baby smiles, clucks, and grabs the phone, to which Rihanna says, "Are you trying to get Mom's phone?"
The singer's first video on the network has already been viewed almost 13 million times, with around 3.7 people clicking the heart icon to "like" the video.
The 34-year-old announced in January that she was expecting a child with rapper A$AP Rocky.
Her son was born in May, but no other information, such as the child's name, was made public.
Barbados-born singer Robyn Rihanna Fenty has become a billionaire in recent years.
In addition to her musical successes, she also founded successful cosmetics, lingerie and fashion brands.
