Hollywood actress Liv Tyler has attacked celebrity mothers for claiming to shed their pregnancy weight immediately after giving birth - accusing them of setting a bad example to their fans. The LORD OF THE RINGS star refused to diet after having baby MILO in December 2004, and she finds it ridiculous that celebrities will lie about their post-baby weight loss. She tells Britain's Cosmopolitan magazine, "It's so hard to lose your baby weight! Everyone makes it look like it just drops off and everyone in magazines is so skinny three weeks later and says 'Oh, I'm just running around after my kid'; it's total bulls**t! "I don't know one woman who woke up three weeks later and was a rail."
