Yahoo apologizes for an earlier announcement inviting users to watch the singer's Friday headlining performance in Las Vegas.

Taylor Swift's headlining set at the Rock In Rio festival will not be live-streamed, despite earlier announcements.

A tweet by YahooMusic, apologized "for any confusion" from a message posted four hours earlier encouraging users to tune in to YahooLive to see Swift, Ed Sheeran, Jessie J and more perform at the Las Vegas concert's "pop weekend."

Metallica Dominates With Raucous Headlining Set on Day 2 of Rock in Rio USA It's unclear whether the stream was canceled or if Swift had not consented to a broadcast of her set, which would ostensibly be a first look at her 1989 world tour, officially kicking off May 20 in Bossier City, Louisiana. Swift's rep has not yet responded to Billboard's request for comment. The May 8 - 10 debut of the Brazil music fest, which featured performers Metallica, No Doubt and Linkin Park, drew 82,000 people to the Las Vegas strip where a 40-acre "City of Rock" has been erected that contains an open-air concert venue, Ferris wheel and a zip line that stretches in front of the Main Stage. Update: Sources tell Billboard it was "a decision from management" not to allow a live-stream of Swift's performance.
