There were reports that the 26-year-old actress had been roped in for the show, which sees a group of celebrities holed up in a house for three months with multiple cameras watching their every move.
"The news is completely untrue and baseless. I was never approached by Bigg Boss and I am not a part of it," Pracchi said in a statement.
The actress, who started off her career in showbiz with TV soap "Kasamh Se", was last seen in Sanjay Dutt-starrer film "Policegiri". Pracchi will star next in "Rock On! 2".
