Actor Aamir Khan, who will share screen with Genelia D'Souza in the upcoming film, Sitaare Zameen Par, opened up on romancing the actress who is 23 years younger to him. "We’re both playing characters in their early 40s. She’s around that age...I’m 60, but we have the advantage of VFX...So, age is not a barrier for actors anymore," he stated.
