New claims are suggesting Scarlett Johansson is “the biggest prima donna.”

The beautiful actress, who recently joined up with director Woody Allen for the third time in ‘Vicky Cristina Barcelona’, is said to have changed severly since she first appeared in Woody’s 2005 movie ‘Match Point’.

A source revealed; “The producers have been saying that Scarlett isn’t the same and that she has turned into the biggest prima donna.

These are the same producers who worked with Scarlett on ‘Match Point’. Everyone back then said she was a sweetheart but now they say, ‘Scarlett has let it go to her head.’”

However a representative for Scarlett is denying these claims telling the New York Post newspaper, “Scarlett loves the movie and enjoyed working with everyone on it.”

Meanwhile, Scarlett recently admitted she hates having to leave her movie characters behind once shooting the film has wrapped.

She said, “I can’t help thinking about what happens to them after the film ends. I care about them. I usually assume that my character lives happily ever after.

In my mind every character I play ends up living in the suburbs with two-point-five children. That’s just the way that I see it. I’m always thinking, ‘I’m sure they’re OK.’ ”

In other news, Scarlett recently slammed Hollywood’s treatment of older actresses insisting many women see their careers “wilt” after they get past a certain age.

The young star is upset that the majority of the movie industry relies on looks and has blasted film bosses for ignoring the talents of several mature actresses and she also believes this rule doesn’t apply to men.

As male actors get older they don’t lose their popularity with casting directors.

She said; “Women kind of wilt as men achieve as they get older, like wine.

It’s like, ‘Oh she’s past her prime and can’t play a sex symbol’.

It’s just a preconceived notion about women in general and particularly in this industry. It’s a very, very vain industry.”
