Taylor Swift Sings ‘All Of Me’ With John Legend At Los Angeles Concert

Taylor Swift fans enjoyed yet another legendary guest performance Tuesday.

R&B crooner John Legend hopped onstage during Swift's Los Angeles concert for a surprise rendition of his 2013 mega-hit "All of Me."

Swift, who sang along as Legend belted the passionate lyrics and keyed the piano, revealed after the show that the sparkling performance wasn't originally planned.

"I heard @johnlegend and Chrissy (Teigen) were on the way to the show & called and asked if John felt like playing 'All of Me,'" Swift shared on Twitter early Wednesday morning.

The surprises weren't over, either. Later on in the show, Swift welcomed indie artists Beck and St. Vincent onstage, and then sang Beck's single "Dreams" as a dazzling display of pyrotechnics went off behind them.

"St. Vincent casually slaying that guitar solo while pyro goes off in the background," Swift captioned a photo from the performance on Instagram. "Beck and I having a dance party. I don't know how to process any of the events of tonight."

Tuesday's talented trio of singers joins the long list of surprise guests to appear during Swift's critically acclaimed "1989" tour this summer.

In her previous three shows alone (all in L.A.), the "Shake It Off" singer has brought aboard Ellen Degeneres, Alanis Morissette, Chris Rock, Matt LeBlanc and Mary J. Blige, among others.

Even Lakers legend Kobe Bryant joined in on the fun, presenting Swift with a banner honoring her 16th sold out show at the Staples Center on Friday.

The star-power has even extended to the stands, where Swift's boyfriend and EDM icon Calvin Harris was spotted during her show Monday. Swift mouthed "I love you" in his section of the crowd during the show, leading many fans to believe she was giving him a not-so-subtle shout out.

Swift wraps up the Los Angeles leg of her tour with her fifth and final performance at the Staples Center Wednesday.

Chances are a whole new host of unexpected celebs will join her onstage for the finale.
