Despite not having proof of address on her - because her ID and passport are registered to her business address - she claims multiple police officers along the way assure her she would be able to get into Malibu if she filled out a few forms.
However, she wrote: "The officer by Kanan [the street leading into Malibu] was a complete and total a**hole. When I told him I could pull up proof of water bills or whatever I could find, he didn't even look at me and just told us to turn around.
'He assumed we were looters trying to get into Malibu to steal. He didn't say he wasn't letting us into Malibu because of looting, he LITERALLY called us looters. He told us to turn around an cooperate or we were getting arrested.'
Ireland went to to compliment the other officers she spoke to, saying they acted calmly and professionally without making accusations.
She also thanked firefighters and police for helping to put out fires and keep people safe, before branding the one officer who offended her "a d**k."
As for her house, she said she has no idea whether it is still standing but revealed all of her pets and her boyfriend were out of harm's way.
Then, Ireland turned her rage on Donald Trump and a pair of tweets that the President issued over the weekend, attempting to turn the fires into a political issue.
The first, on Saturday, read: "There is no reason for these massive, deadly and costly forest fires in California except that forest management is so poor. Billions of dollars are given each year, with so many lives lost, all because of gross mismanagement of the forests. Remedy now, or no more Fed payments!"
A second, issued after a backlash, added: "With proper Forest Management, we can stop the devastation constantly going on in California. Get smart!"
Ireland retorted: "At this point, calling Donald Trump an a**hole or being surprised by his reaction to any of these fires is a waste of energy. All you really can do is feel sorry for him.
"He's a sad, disgusting, classless, angry, inhumane, vile, abusive, atrocious, dull, vain, patronizing, thoughtless, unintelligent, Jabba-the-Hutt-looking excuse of a creature from the depths of hell. What do you expect from someone like that?"
Ireland was not the only celebrity to be affected by the fires, as Robin Thicke, Gerard Butler and Miley Cyrus revealed that their mansions were all destroyed in the fire.
Meanwhile Simon Cowell was evacuating on Sunday night as strong winds fanned the flames towards his $23million home.
Kim Kardashian, Kanye West, Will Smith, Caitlyn Jenner and Lady Gaga were also forced to flee as the flames approached, though it is thought all of their homes are intact at this point.
The Woolsey Fire was burning largely out of control on Monday morning, having ripped through 90,000 acres and destroyed 370 buildings.
Two people have also died in the blaze after their bodies were found inside a burned-out car stranded on a long driveway.
In total, 170,000 people have been evacuated with a further 57,000 buildings under threat, Cal Fire reported.
