With controversial show "Bigg Boss 9" gearing up for the finale (24 January), the top five contestants -- Prince Narula, Mandana Karimi, Rishabh Sinha, Rochelle Rao and Keith Sequeira -- are ready to compete against each other to win the trophy.

Like every season, the finale of "Bigg Boss 9" will also be a grand affair with several celebs making an appearance on the show.

While speculations were doing the rounds on if Katrina Kaif will promote "Fitoor" on ex-boyfriend Salman Khan's show, on Sunday's episode, Salman confirmed that Katrina will be seen on the grand finale along with her "Fitoor" co-star Aditya Roy Kapoor.

The last time Katrina appeared on Salman's "Bigg Boss" was to promote the Farah Khan directorial "Tees Maar Khan" (2010). With Katrina appearing on Salman's show after several years, it would be interesting to see the ex-couple together on-screen.

It should be mentioned that over the last weekend, reports of Katrina and Ranbir Kapoor breaking up took the internet by storm. There were also rumours that Katrina spoke to Salman before breaking up with Ranbir

Besides the "Fitoor" actors, others who will add charm to "Bigg Boss 9" grand finale are Mouni Roy of Colors' popular show "Naagin", Siddharth Nigam of "Chakravartin Ashoka Samrat" and Jigyasa Singh of "Thapki Pyar Ki".

The cast of "Comedy Nights Bachao" including Bharti Singh, will also be on the finale to entertain viewers with their funny antics.
