Bow Wow (real name Shad Moss), 32, shared a photo of Joie, 30, posing in a fierce ensemble.
"I am so proud of this woman!" he wrote next to the IG snap. "When i say get it on ya own she did that. A true inspiration for all women."
"I know you hate when I post you because of the attention, but one must acknowledge a REAL 1," he continued. "My friend my patna my ace the one who tells me to tighten up when I need it."
"The mother of my daughter is killing sh**!" he said before finishing with "Ladies if you tryna get that body right... you better holla at her."
Joie didn't respond to Bow Wow's words in the comments section as of Saturday, August 31. She did, however, post several fitness-related Instagram Stories before and after he shared his post about her.
Bow Wow and Joie dated on and off between 2010 and 2017. The former couple share a 8-year-old daughter named Shai.
Other women that the "Thank You" rapper has dated include Keyshia Cole, Ciara and Erica Mena, the latter of which he was previously engaged to.
