Why did Mona Lizza Change her name?

It is really mind boggling that Mona Lizza a renowned Pakistani Lollywood actress would change her name to a completely English name – Sara Loren. She is not at all related to Sophia Loren and neither is she Italian or English.

Then what happened! Even her name Mona Lizza was never her own! But she was accepted by Pakistanis as Mona Lizza, then why change to go to Bollywood.

I think one must be true to their identity, and if a name change is needed then once is good enough, not every 10 years. So Mona Lizza, we mean Sara Loren what ever the reasons are, do let us your fans from Pakistan know!
