Kangana, who does not attend Bollywood award shows (and wasn't present to collect the Filmfare prize for Best Actress she won this year), looked ravishing in a mauve cut-out Bibhu Mohapatra dress with a cape.
Kangana received the Rajat Kamal for Best Actress for her acclaimed performance in 2014's Queen while Kannada actor Vijay received the Rajat Kamal for Best Actor for Nanu Avanalla Avalu.
Kangana, for whom this is the second National Award after her Best Supporting Actress win for 2008's Fashion, spoke to NDTV a few hours before she received the award. She said she was thrilled when she heard she'd won and revealed that she was in a very fulfilling phase of her life where everything seemed picture perfect. "I am very happy that there is pressure on me, I think I can deal with it," she said.
Director Chaitanya Tamhane and actor-producer Vivek Gomber received the Swarn Kamal for Best Feature Film for Court.
Vikas Bahl, who directed Kangana in Queen, collected the award for Best Hindi Film along with director Vikramaditya Motwane, who co-produced the film with Anurag Kashyap.
Director Omung Kumar received the award for Best Popular Film Providing Wholesome Entertainment for Mary Kom. He had earlier told NDTV when the National Awards were announced, "It's the biggest high anyone could get. I'm top of the world, a dream come true, my first film and this honour is overwhelming."
Director Vishal Bhardwaj, whose film Haider won in five categories, collected his awards for Best Dialogues and Music Direction. He told NDTV prior to the ceremony, "I am feeling extremely happy and elevated. I don't think any film has won five awards, it's a matter of honour for me."
Singer Sukhwinder Singh, who collected the award for Best Male Playback Singer, gave a power-packed performance of Bismil from Haider. Singer Uttara Unnikrishanan, had the audience mesmerized with her soulful number Azhagu, from the Tamil film Saivam, which fetched her Best Playback Singing (Female).
Haider fetched choreographer Sudesh Adhana the Best Choreography Award, while Dolly Ahluwalia received her award for Best Costume Design for the same film.
Tamil actor Bobby Simha received the Rajat Kamal for Best Supporting Actor For Jigarthanda and actress Baljinder Kaur received the Swarn Kamal for Best Supporting Actress for the Haryanvi-language Pagdi The Honour.
Dhanush received the National Award for producing the film Kaaka Muttai which won the Best Child Actor and Best Children's Movie.
Chotushkone director and writer Srijit Mukherji received the Rajat Kamal for Best Original Screenplay.
Actor Shashi Kapoor, 77 and unwell, was unable to travel to Delhi to collect the Dadasaheb Phalke Award. He will receive it in Mumbai on May 20. A special film on the actor was shown at the ceremony.
The president also congratulated the actor. "My special congratulation is to Shri Shashi Kapoor. His contribution to cinema has been tremendous. He is a true living legend. He began his career as a child artist in the films Aag and Awara, and then we saw him as a flamboyant hero in many blockbuster films," he said.
Actors Pallavi Joshi and Rajat Kapoor hosted the presentation ceremony.
The National Awards were announced on March 24.
