Sharing a picture of the celebrant on her Instagram page, the excited mother showered encomiums on her daughter.
Mercy Aigbe also prayed for Michelle, and reaffirmed her love for the celebrant.
She wrote, “Look who turned 21 today!
My hunny bunny, my chocolata, my caramel topping, the apple of my eyes, my sweet heart, my angel, the first fruit of my womb.
“By this time 21 years ago, I’ve pushed you out. My big baby, the best gift from God to me, my jewel, the best daughter ever, my smart, very intelligent daughter, my source of strength, my world, my everything.
“You will continue to be the head in all you do. The lord will prosper you beyond measures. You will continue to grow from glory to glory.
“The lord will guide and protect you. No evil shall befall you. You shall thrive and be successful even beyond my expectations, in Jesus mighty name! I love you my princess.”
Mercy welcomed Michelle on July 11, 2001, with a former lover, before the actress got married to her now estranged husband, Lanre Gentry, in 2013.
It was earlier reported that Mercy Aigbe left Lanre Gentry over allegations of domestic violence and infidelity in 2017.
Mercy Aigbe, however, unveiled her new husband, Kazim Adeoti, on Instagram, in January 2022.
Michelle Aigbe owns her own beauty brand, which has earned her some recognition in the beauty industry.
The 21-year-old is also studying at the University of Manitoba, Canada.
