Now that Kareena Kapoor's sleek size-zero look in her latest film 'Tashan' failed to work wonders at the box-office, she has added a few pounds for a new look in her forthcoming 'Main Aur Mrs Khanna'.

A source close to Kareena has confirmed that she has put on weight for her new style for the film, which also stars brothers Salman and Sohail Khan in pivotal roles.

''Tashan' had action scenes and required Kareena to be thin and to look fit. So she cut down on her weight. But her character in 'Main Aur Mrs Khanna' is entirely different.

'Kareena plays a housewife and has kept her style keeping the character in mind,' the source was quoted as saying.

Incidentally, Kareena's favourite designer Manish Malhotra, who tailored her look for Karan Johar's 'Kabhi Khushi Kabhi Gham', said: 'Bebo (Kareena) has never looked better.'

Although the actress' prescribed diet includes paranthas, momos, cheese, pasta and bananas, which are mostly considered fattening, it is her daily practice of yoga that keeps her fit.

'She is feeling more energetic, healthier and sexy now. Kareena wants her fans to know that it is only due to her dedication and discipline about her eating and fitness habits that she could achieve her figure,' the source said
