"I feel contestants have already started playing so many games in 'Bigg Boss' and everyone is looking so well-planned. They should just let themselves be, like I was there with a very careless attitude," the 42-year-old said at the birthday bash of Yogesh Lakhani.
"Here everyone is taking each step very cautiously. So, there is not much spice," he added.
He advises the contestants to be natural on the show as the audience likes it that way.
"But I think some new people will enter the house. You should be very natural there. The audience likes to watch real things. You can't plan every move," Ravi said.
Ravi has four favourite contestants.
"It's too early but Gauahar Khan is looking very strong, so is Tanisha Mukherjee and Armaan Kohli. Ratan Rajput is also looking very strong," he said.
