On 30 May 2014, Monica converted to Islam. At a press meet, she said, "I didn’t convert for the reason of love or money, I am not such a person. I like Islamic principles, so I converted to Islam. I will intimate about my marriage to media once arranged by my parents and I really thank my dad for his full support. I was not convinced to change my name but finally, I have changed my name to M.G. Rahima (M.– Maruthi Raj (Father), G. – Gracy (Mother)). Hereafter, I won’t act in films". Monika’s father is Hindu and the mother is a Christian.^[5]

Rahima tied the knot with Malik. Malik is a Chennai-based entrepreneur, who hails from Madurai. It is said that Malik also happens to be the son of Rahima's father's close friend. Malik is into import and export of electronic items.^[6]
