Was this done without permission? Was it just good PR? TMZ got to the bottom of it.
'TMZ obtained an email from the Hollywood Chamber of Commerce, which owns the Hollywood Sign. The Chamber made it clear ... her production company was notified she could not shoot the sign or use the video without getting prior approval from the Chamber.
Sydney climbing the hill and the sign and then festooning it with bras could even put her in legal jeopardy for criminal trespass and/or vandalism.
The Chair of the Hollywood Chamber of Commerce tells TMZ ... "There was no permission granted to do this as is required." We asked if they would file a police report for trespass and/or vandalism ... we got no response.' - via TMZ https://www.tmz.com/2026/01/26/sydney-sweeney-climbs-hollywood-sign-bras/
