Siddharth's Telugu film, Oh My Friend, co-starring Shruti Haasan, Hansika and Navdeep is going to be released in Tamil as Sridhar. STR caused a buzz when he agreed to render one of the tracks composed by good friend, Thaman. Now it is Sivakarthikeyan's turn to lend his voice to Siddharth.

After the super success of Kadhalil Sodhapuvathu Yeppadi, Siddharth has become very busy and did not have the time to dub for the Tamil version. Sivakarthikeyan stepped in and did the dubbing for him. He did such an excellent job that the entire team praised him and expressed their gratitude to him.
