She inaugurated Jaya Smriti at the Nehru Center here Friday but postponed the subsequent two days' programme following Thackeray's death Saturday.
"Due to sad demise of Shri Bal Thackeray, Jaya Smriti on 17 and 18 November is postponed. I hope you all who love me will stand by me in this situation," Hema tweeted.
The three-day drama, music and film extravaganza has been a regular annual event since 2010. The function is a tribute to Hema's mother - Jaya Chakravarthy.
The 64-year-old was supposed to be part of the performances along with her younger daughter Aahana. She has not announced the new dates of the event.
