Sydney Sweeney snuck up an L.A. mountain a couple of days in the past, climbed the long-lasting HOLLYWOOD Signal, and laced it with bras … and she or he could have gotten in hassle with the legislation.

TMZ obtained video of the “Christy” star scaling what seems to be the “H” with a handful of bras. A manufacturing staff is filming as Sydney makes her means up within the cloak of darkness.

Sydney and her crew made their method to the highest of the letters and strung up a clothesline of bras. Sweeney is gleeful as she surveys her helpful work.

As for why she did it … sources say it is a video to promote the launch of her new lingerie line. As TMZ reported, Jeff Bezos is an investor, so it is properly funded for certain. That is the Bezos connection that acquired her an invitation to the Bezos/Sanchez wedding ceremony final summer season.

Now the issues. We have discovered Sydney acquired a allow from FilmLA to shoot the Hollywood Signal, however she didn’t have permission to the touch or climb the signal itself … and, just like the bras, the allow had strings connected.

TMZ obtained an e mail from the Hollywood Chamber of Commerce, which owns the Hollywood Signal. The Chamber made it clear … her manufacturing firm was notified she couldn’t shoot the signal or use the video with out getting prior approval from the Chamber.

Sydney climbing the hill and the signal after which festooning it with bras might even put her in authorized jeopardy for felony trespass and/or vandalism.

The Chair of the Hollywood Chamber of Commerce tells TMZ … “There was no permission granted to do that as is required.” We requested if they’d file a police report for trespass and/or vandalism … we acquired no response.
