Did Amrita Singh opt out of 'Mubarakan' because of Sara Khan?

Since the time 'Mubarakan' has been announced, it's been in news for some reason or the other. One such news that got everyone excited was the coming together of Amrita Singh and Anil Kapoor. But the excitement was short lived as Amrita Singh opted out of the project few days back.
Though the actress cited date issues, sources reveal that the actual reason behind Amrita choosing to back out of the project is Sara Khan's debut film.That's right, Amrita and Saif's daughter Sara is gearing up for her big Bollywood debut and at this point Amrita felt that she should focus more on getting her daughter the right debut film.
Reports also suggest that Amrita had recently signed a couple of other films, which she has now opted out of for her daughter's sake.
