Karan, 31, said he is looking forward to his new innings in life.
"Ankita and I are getting married and this is a new chapter in my life. I am looking forward to it without a doubt, can't wait, she is a beautiful girl, a friend more than that my 'would be' wife," he said in a statement.
The Kolkata-born actor is currently sharing the screen space with Ankita's father Abhay Bhargava, who plays Karan's onscreen father on the Ekta Kapoor show.
The actor was earlier linked to former 'Bigg Boss' contestant Kamya Punjabi.
