Arnold Schwarzenegger's estranged wife Maria Shriver has weighed into the war between the paparazzi and celebrity mums, insisting both sides need to work something out.

The former newswoman admits she's conflicted over the battle as Halle Berry and Jennifer Garner fight for new laws to keep photographers away from their kids, but she agrees with the actresses that the paparazzi have become too aggressive.

She tells Entertainment Tonight, "I'm a member of the press and I'm a big believer in freedom of the press, but I think for many people the paparazzi go too far. They get a lot of money for those pictures.

"I think that there probably could be more communication between the two sides."
