The iconic Hollywood sign has a new neighbor mooving in ... because there's a giant cow in the middle of the landmark.
As you can see, the sign was vandalized Friday with an image of a dairy cow taking over the middle of the first 'O.' Law enforcement sources tell TMZ ... 3 people have been arrested for trespassing, with a police helicopter helping officers track the suspects as they made their way back down the hill.
We're told the alteration to the sign was done as a joke, and not as a protest for or against bovines.
There's a band out of Los Angeles, called Junior Varsity, appearing to take credit for the vandalism. JV just released its debut single, "Cold Blood," which features a dairy cow as the cover art and their social media accounts have been telling folks to "Look for the signs."
