Twinkle says of the two she might be the one who is well read, but the "Airlift" star is street smart.
"He (Akshay) doesn't read. I always say you need to read to be smart or successful but he doesn't read. Despite that, he is really smart. He is smart in a different way than I am. I am probably better read, but he is street smart."
"He is better with numbers than I am. His understanding of people, the way business works, is greater than me. He is extremely confident," says the actress.
The actress said smartness in today's age can't be defined in a specific way and added that even the film fraternity has a mix of smart and "very dumb" people.
