The 33-year-old former glamour model vented her anger on Twitter at being asked to hand in her mobile phone to organisers inside the Cineworld O2.
All guests had to have their phones confiscated to ensure no shots of the highly-anticipated film were leaked to the public.
Price wrote: "What an absolute joke! How many parents of children/disabled children know the importance of being able to be contacted if something happens in an emergency???
"At the hunger games prem were told to hand our mobiles in... we explained the importance to have our mobile phones for obvious reasons and they said no!
"They treated us like s**t and we are doing them a favour giving them FREE publicity! My kids are more important."
Former Liberty X star Michelle Heaton added weight to Price's criticism, tweeting: "What a shame we had to leave #hungergames prem. as a mum of an 9wk old and Katie a mum of Harvey, we couldn't possibly hand our mobile phones in, in case of emergencies! X x"
