Actress Katrina Kaif has stepped down as the brand ambassador of Indian Premier League team Royal Challengers Bangalore because she feels she will not be able to do justice to her responsibilities towards the team due to the IPL-4 matches clashing with her shooting schedule.

The Banglaore IPL team had extended her appointment as the brand ambassador for seasons three and four, but she is unable to continue as she would be shooting for Yash Raj Film's Mere Brother Ki Dulhan during IPL-4 beginning April 8.

The film's shooting is in Agra and, therefore, it won't be possible for her to make appearances to support the team and hence the decision to step down as brand ambassador, a press statement said.

'Katrina Kaif is a thorough professional and believes in giving her 100 percent to all her commitments. She is an avid sport's enthusiast and wanted to be present for all of the team's matches to cheer them on,' said a source.

'However, since she will be shooting during IPL-4, she has decided to opt out of the Royal Challengers since she wouldn't be doing justice to them,' the source added.

Mere Brother Ki Dulhan is Ali Abbas Zafar's directorial debut and Katrina has teamed up with actor Imran Khan and Pakistani singer-actor Ali Zafar in the movie.
