Actor Nawazuddin Siddiqui has dedicated his Best Supporting Actor honour, which he won at the International Indian Film Academy (IIFA) Awards here, to his Mom co-star Sridevi, who was posthumously awarded the Best Actor in a Leading Role Female title.

"It was once in a lifetime opportunity to work with the first female superstar Sridevi and I dedicate my award as a tribute to her," Nawazuddin tweeted on Monday, a day after the IIFA Awards ceremony in Bangkok.
