Taylor Swift and John Legend Perform "All Of Me."

Taylor Swift, Beck and St. Vincent perform "Dreams."

Taylor Swift brought John Legend on her ‘1989 World Tour’ stage at Los Angeles Staples Center Tuesday for a performance that put Swift on the microphone and Chrissy Teigen’s husband on the piano keys, according to Daily Mail.

And it all happened shortly before show time, according to Time.

“I found out John and Chrissy were coming thirty minutes before I went on and called Chrissy and asked her if John would perform,”Swift informed the crowd.

The experience is surely one the Pennsylvania native will treasure for the rest of her life, along with being able to stand side by side with other music artists like Beck and St. Vincent - just prior to collaborating with the legendary R&B singer.

“Getting to play ‘Dreams’ with @Beck and @st_vincent is something I’ll remember forever. I can’t even express it,” Swift posted on Twitter.

St. Vincent also enjoyed the epic opportunity to perform with the popular vocalist.

“Had the most MAGIC time with the most brilliant and venerable @taylorswift13 & @Beck tonight. #DreamsComeTrue,”the rock band said on Twitter.

Swift has also welcomed Miley Cyrus and Alanis Morissette into the spotlight on her tour.
