Akshay Kumar to have a brunette and blonde from Cape Town, egging the participants on to give the tasks their best shot

Sheila and Munni have jumped into the Khatron Ke Khiladi 4 fray. And no, we don't mean Katrina Kaif and Malaika Arora Khan.

KKK4 host Akshay Kumar will have a brunette and blonde, Andrea and Jamie, from Cape Town, South Africa, egging the participants on to give the tasks their best shot.

Andrea is a model while Jamie is an undergraduate in science. And the Khiladi preferred to refer to them as Sheila and Munni.

Says a source, "It was the channel's decision to bring in local flavour as the show is being shot in SA. The girls will motivate and encourage contestants as they perform dangerous stunts."

Akki announced their entry dramatically. He shocked the 13 female participants by telling them that the season would have 15 gals. "Their walking in was just as dramatic.

'Munni' and 'Sheila' walked toward the contestants to the opening tune of the La La La track from Saagar." Adds the source, "It was Akshay's idea to have his mother-in-law's Saagar track included."

While these two might add some more oomph factor to the show, the other purpose of having the both is that they will be rewarding the best performing male partners of the contestants with a 'jeet ki jhappi' and 'preet ki pappi'.
