Actress Kajal Aggarwal, who is busy with two films in Tamil, believes in falling in love with a person blindly before getting hitched. I'm not very romantic — I'm a practical person in real life. I have restricted the romantic side of me to films. I like doing sweet things, but can't keep saying 'I love you' always. But, yes, I have an open mind, and am ready to mingle. A proper compatibility should exist between the person and me. I have been single for quite some time now. I have not been in a relationship for the last three years, which is a long time," she was quoted saying to a leading daily.
