Taylor and Kylie's billboard turf war on Santa Monica Blvd. in WeHo proved to be short-lived ... Taylor's billboard pimping her single "Look What You Made Me Do" has been replaced by Sam Smith, whose new music drops Friday.
It's unclear when the billboard was replaced ... but it makes sense after Taylor easily shot up to No. 1 on Spotify's global chart with over 44 MILLION streams. For what it's worth, "Life of Kylie" has struggled in TV ratings.
Take it away, Sammy!
