Actress Sonam Kapoor started off her speech with a “namaste” at the coronation ceremony of King Charles III in Berkshire on Sunday as she dazzled in a white floral floor-length gown by Anamika Khanna and Emilia Wickstead at the Windsor Castle ground.

"Historic moments call for fashion moments. I'm honored to mark the unforgettable occasion of the #Coronationconcert by wearing the collaborative sion of two of the most incredible designers from the two countries I'm lucky to call home," she wrote on Instagram alongside her pictures from the event.

At the Coronation concert on Sunday, the 37-year-old introduced several choir performances including The Bahamas Youth Choir, Steve Windwood and Virtual Commonwealth Choir.

“Our Commonwealth is a union. Together we are one third of the world’s people, one third of the world’s ocean, one quarter of the world’s land. Each of our countries is unique. Each of our people is special. But we choose to stand this one. Learning from our history, blessed by our diversity, driven by our values and determined to build a more peaceful, sustainable and prosperous future for everyone, where every voice is heard,” Sonam said.

Sonam's 'historic moment' got support from her family members and friends who cheered for her on social media. Sonam's mother, Sunita Kapoor, shared a video of her speech on Instagram. Her father, Anil Kapoor, also shared the video on his Instagram story and wrote, "Making us so proud."

Sonam's cousin brother Arjun Kapoor, uncle Sanjay Kapoor, aunt Maheep Kapoor and Bhavana Pandey as well as Shanaya Kapoor congratulated the Bollywood star on Instagram. "👏👏👏 this is such an honour," actress Neelam Kothari Soni commented on Sunita Kapoor's post.

Sonam will be seen next in Shome Makhija’s Blind after taking a four-year break from the movies. The film, which has been adapted from the 2011 Korean movie of the same name, also stars Purab Kohli, Vinay Pathak, and Lillete Dubey.
