As Taylor Swift attempts to keep her ongoing 1989 Tour in the headlines thanks to surprise guests at every show, the pop star brought out Beck, John Legend and St. Vincent during her show Tuesday night at Staples Center in Los Angeles.

It was Swift's fourth sold-out show at the arena, where she first recruited Legend for a live duet of "All of Me" earlier in the show.

Beck and St. Vincent joined Swift later in the night to perform a rendition of Beck's latest single "Dreams," with St. Vincent on guitar.
