Mega Powerstar Ram Charan speaking to TV9 after launching Happi mobiles said, happiness is very important and wished the brand success. He said the brand will be numero uno in short time. Ramcharan said his moments of happiness are having a disciplined life, a healthy mind and going to work on time. He said it is rare to do workouts with Upasana as her timings are different. Charan said they (Mahesh Babu and Jr NTR) don't party at all and added that they just sit and have dinner and go home.
