Sneaky! According to a press release Taylor Swift was not set to perform at the I Heart Radio awards last night, but she shocked us all when she took the stage and sang with Madonna! And she may have walked away with the Artist of the Year Prize (and two other honors), but we kinda love the fact that she got lost on stage. She may be beautiful and talented, but she's gets nerves just like the rest of us! Taylor later posted a hilarious Instagram photo of herself and added, "Living proof that you can be the @iHeartRadio Music Awards Artist of the Year and also a super embarrassing person!"

When walking up to the stage to accept the award for Best Lyric for “Blank Space," Taylor had a bit of a fangirl moment when she met Jane the Virgin's Gina Rodriguez. "I’ve wanted to meet you for so long — you’re amazing," Swift gushed. But then something totally hilarious happened -- Tay Tay didn't know where she was supposed to go next! A confused Swift asked Rodriguez, "What do we do? Do we just walk off?"

Later in the evening the 25-year-old singer busted out her guitar and joined Madonna onstage for Madge's hit "Ghosttown," and though the two sat on stools in the beginning, they eventually rocked out onstage and shared a big hug before walking offstage together. Madonna later tweeted, "My new favorite guitar player! Thank you Taylor! Just you and I in #ghostown ❤️#rebelhearts." Awww!


Earlier this year Madonna told Access Hollywood, "[Taylor] writes some damn catchy pop songs. Can't get them out of my head." When Taylor learned the news, she told the show "Stop! I will pass out. Oh my God! I've been so scared to meet her because it means so much to me."

And just as we predicted, there's an awesome video of Taylor shaking it to Snoop Dogg's take on "Peaches and Cream" ... get it girl!
