Uday, 33, was found hanging from the ceiling in his flat.
Here's what they had to say:
Music composer R.P. Patnaik: Uday, you should not have done that. You still have many fans who like you for what you are. There was still a career to move on. Committing suicide is not a solution for a struggle. You should have fought till the audience realised that you are a self-made star. Our songs have been all-time superhits. You will remain in the hearts of the people forever.
Vimala Raman: R.I.P (rest in peace), Uday Kiran my first co-star in my career and a sweetheart. You will be missed.
