Sara Ali Khan was seen with mentor Karan Johar at Shahid Kapoor's 36th birthday bash.

All eyes are on Sara Ali Khan's big Bollywood debut. Saif Ali Khan and Amrita Singh's daughter has been roped in by Dharma Productions for her big screen debut and the 21-year-old will soon begin prepping up for her first Bollywood film. And the star kid was recently seen with her mentor Karan Johar at Shahid Kapoor's pre-birthday bash.

Bollywood's who's who was invited to the big bash and Sara was also on the guest list. Clad in a monochrome dress, Sara looked gorgeous as she made her way to the party with Karan Johar.

In fact, the two happily posed for the shutterbugs. It's been a while since Sara's debut has been making news but the details of her project have been kept under the wraps.

Meanwhile Sara's dad Saif Ali Khan has put all rumours to rest about disapproval of his daughter Sara being launched by Karan Johar and said he would be more than happy if the Ae Dil Hai Mushkil director gives her a film break. "I would love Sara to be launched by Karan Johar. He is one of the best that we have," Saif, 46, said in a statement.

The Phantom actor added, "I keep reading various reports where I am supposedly averse to her getting launched by Karan because she will apparently become another Alia Bhatt. "If Sara becomes as successful as Alia is then it will be a matter of pride and happiness for all of us," he added.

Sometime back Saif in an interview to Mumbai Mirror had said that he doesn't want to dissuade his daughter from joining film as she craves this excitement, creative fun and glamour.

He told the daily, "Who's to blame, it's in her genes. I remember on the first world tour we were on together, I spotted her peeking through the curtains backstage to watch the actors dancing on stage, mesmerised. That's when she decided this is what she wanted to do. Cinema has changed since and she's also realised there's a lot of angst in the profession, specially if you have not quite arrived yet. I worry about that, but what can I do?"
