In the January 1 episode of Bigg Boss 18, Avinash Mishra expressed concerns about facing legal trouble after leaving the house. Tensions between him and Chaahat Pandey, his co-contestant and former co-star, escalated when Chaahat's mother entered the house and accused him of inappropriate behavior.

Chaahat’s mother confronted Avinash over a comment he made, claiming Chaahat wanted to see him shirtless. She said this remark hurt her family and caused people in their village to make fun of her daughter's character. She also called Avinash a "womanizer," referencing Kashish Kapoor, who had previously used the term during an argument with him. Avinash apologized for hurting her feelings but denied being a "womanizer." He added that such accusations on national television were unfair.

Chaahat’s mother criticized Bigg Boss for setting up a court-like session for Avinash and Kashish’s argument but not addressing his comments about her daughter. She warned, "There are courts outside, and people are watching."

Later, Avinash shared the incident with the housemates, joking about being dragged into legal battles after the show. He admitted he had no lawyer or legal contacts and quipped that he would call fellow contestant Karan Veer Mehra for help if needed.

The episode highlighted the ongoing tension between Avinash and Chaahat, with emotions running high and accusations adding to the drama inside the house.
