Listen to Taylor Swift on iHeartRadio | Listen to Cher Lloyd on iHeartRadio

Taylor Swift doesn't mind sharing the spotlight. 

During her Monday night concert at the Staples Center in Los Angeles, she brought on not one, but two, surprise guests.  British pop singer Cher Lloyd was the first to join her on stage, performing her single "Want U Back" with the country star. 

Later, Taylor introduced Sara Bareilles who she also joined on her latest single "Brave."  Fan videos posted to YouTube show Taylor singing Sara's praises, calling her a singer-songwriter "who's so incredibly talented it's ridiculous."  She then called the song "so original" and  "beautifully written." 

"Brave" made headlines last week when Katy Perry was accused of ripping it off on her single "Roar."  Some sites, like "The Huffington Post," are wondering whether Taylor's gracious introduction may have been a subtle dig at Katy - who is currently dating one of her exes, John Mayer.  

Taylor also brought out Tegan & Sara during her most recent concert at the Staples Center to perform "Closer."

And Friday night, Taylor brought out Ellie Goulding to perform "Anything Could Happen"! Check it out
