Saying it like it is!

Kristen Bell has a simple message for friends wanting to coo over her kids — stay away unless you're vaccinated!

The Veronica Mars alum gave birth to her and Dax Shepard's second daughter, Delta, in December 2014, a sister for firstborn Lincoln, 22 months. And the plain-talking mom has some very clear thoughts when it comes to the issue of child vaccination — something on the decline where she lives in Los Angeles.

She explained her pro-immunization philosophy to the Hollywood Reporter, and revealed she even bans friends of hers from visiting newborns unless they are up to date with their own shots.

"When Lincoln was born (in March 2013), the whooping cough epidemic was growing, and before she was 2 months old, we simply said, 'You have to get a whooping cough vaccination if you are going to hold our baby,'" she told the outlet.

The Frozen actress is taking the same approach with her new bundle of joy. "It's a very simple logic,” Bell, 34, insisted to the mag. “I believe in trusting doctors, not know-it-alls," she said.
