New Delhi: Bollywood superstar Amitabh Bachchan on Thursday said that he is all set to return on the small screen as the Kaun Banega Crorepati 5 host on August 5.

"KBC back in August... and this time for a longer duration than last time... and yes welcome to all entrants... come join me," Bachchan wrote on Twitter.

The 68-year-old actor has already shot some promos with Avinash Gowariker and is excited to be sporting ace designer Rohit Bal's creations on the show this time.

Posting a few pictures from the shoot, Big B tweeted, "Promo photo shoot by Avinash Gowariker... brilliant as always... used a new lighting system... excellent... and Rohit Bal on dress."

One of the photos shows Big B wearing a dark brown bandhgala, teamed with a maroon scarf and thick-rimmed glasses. Another photo showed him sporting a sliver blue bandhgala with a cream scarf.

"Designer for KBC on my clothes, by Rohit 'Gudda' Bal... dynamic and so good with colors... a kid in shorts in Srinagar, now celeb!" Bachchan added.
