Salman is hosting the show for the fourth time in a row. Based on the theme of heaven or hell, "Bigg Boss - Saath 7" will go on air Sep 15 on Colors.
"'Bigg Boss' is a good show and my favourite because of Salman bhai. It becomes much more interesting when he hosts it. This time he is coming with a dual personality - one negative and one positive," Dolly told reporters here Thursday at a photography exhibition.
"He is looking very sweet in positive look. He has got a very nice face, he is like a child and will always be. He has a heart of gold," she added.
Bindra created havoc in the Bigg Boss house with her continuous cat fights with other housemates including Shweta Tiwari, who won "Bigg Boss 4".
Though the list of contestants for the new season is yet to be announced, names of TV actors like Pratyusha Banerjee, Gurdeep Kohli, Kushal Tandon and Vatsal Seth are doing the rounds.
