Justin Bieber TOTALLY has baby fever and it's basically the cutest thing ever!

The Yummy singer looks like a total natural as he plays with the 3-year-old son of his main collaborator Poo Bear. The trio spent the day hanging out in Beverly Hills and we've got the feeling Justin is getting just a little antsy to become a dad. Poo Bear has co-written many of Justin's hits including: the Despacito remix, What Do You Mean, PYD, Where Are You Now, All That Matters, and Hold Tight.

Justin has expressed his love of children in the past and has thoroughly enjoyed being a big brother. He and wife Hailey Baldwin have discussed becoming parents in the past we're counting the days until it finally becomes a reality!
