Maybach Music Group leader Rick Ross‘ son is growing fast. The hip-hop star’s former flame Tia Kemp went online this week to share a precious mommy duties moment.

This week, Kemp hit up her Instagram page with a pic of herself alongside their teenage son William Roberts III.

Earlier this month, Tia shared a pic showing just how big their son is in 2019.

A few weeks ago, William Roberts III celebrated his 14th birthday.

Over the summer, Tia shared pics of Roberts looking exactly like Ross’ twin.
