'Dil Mil Gaye', one of the most popular soaps on Star One, had Karan Singh Grover playing the lead role of Armaan Mallik. Karan began his career with Ekta Kapoor's 'Kitni Mast Hai Zindagi' on MTV India. He also participated in the Gladrags Mega Model Manhunt contest in 2004 and won the 'Most Popular' award. He has done several TV commercials and ramp shows, anchored live shows and was also the second runner up on season three of the dance reality show 'Jhalak Dikhla Ja'. He is currently hosting the 'Perfect Couple' show on Channel V.
Karan was married to co-star Shraddha Nigam but within ten months she filed for divorce. Allegedly, the growing attraction between Karan and his 'Jhalak Dikhla Ja' choreographer Nicole Alvares was the reason for their split.
