Sampat had earlier claimed that she had been offered a stint on the upcoming edition of the show but was reluctant as she wanted to attend a women's conference in Brazil.
But the activist has now confirmed that she will be participating and also left for Mumbai today.
"The organisers of Bigg Boss approached me again last night asking for my final response to their invitation and after consulting my people I confirmed my participation," Sampat told PTI over phone.
Regarding her initial reluctance, Sampat (65) said, "Since I had been invited to World Women's Conference in Brazil on October 28, I was in a dilemma over my participation in the reality show."
Sampat said that in case she manages to survive for more than two weeks in the house she would think of cancelling her Brazil plans.
"I can spread the message on women rights and their struggles through the Bigg Boss platform and create awareness since I have been told that in it (the show) the participants get a chance to showcase their actual personality and beliefs," she said.
