Whats in Semifinals of UYAP ????

Semifinals of the Ungalil yaar adutha Prabhudeva show had started today and it looks like its going to be a breathtaking event.. The show will have 2 weeks of semifinals.. so this week is called as Semifinals 1 and each of the semifinals.... the top 4 contestants Sai Pallavi, Nanda, Sherif and Premgopal will be performing dance for 2 numbers. so overall it would be 4 performances from them for the judges to choose the finalists.. Also, there would be only 1 contestant selected for the finals with this round.. and I guess others would join in for wild card round ;)...
