The Wave Foundation has initiated a cause with Flying Unicorn Entertainment to create awareness and try and end domestic violence towards women in the country.
An event is being organised with support from members of the Hindi film industry to give impetus to the cause and to honour six women who have stood up against domestic violence.
Katrina, Harman and Saif will be performing at the event.
"Katrina always likes being part of something meaningful. If her presence brings greater recognition towards the cause she always extends her full hearted support, " said a source on the actress' participation.
The event will be held Saturday in Mumbai.
