The "Euphoria" star is launching Syrn after the Hollywood Chamber of Commerce said she did not have permission to climb on the Hollywood sign in Los Angeles.

SYDNEY Sweeney has shown off her incredible figure while donning some very sexy lingerie as she prepares to take the underwear industry by storm.

"The secret is finally out… say hello to @syrn 🤍 this is lingerie you wear for YOU, no explanation, no apology," she captioned the post, adding SYRN's Jan. 28 launch date.
