Oh hi, Gracie Abrams! The 25-year-old songbird joined Taylor Swift on her third night in Toronto for Saturday's acoustic set. "This is always one of my favorite parts of the night," Swift said in an orange and pink gown at the top of her surprise set.

Taylor Swift thanked fans on Thursday night at her Eras Tour stop in Toronto for the six Grammy nominations she received last week. "You guys did something so amazing over the course of the last few months," she said in a fan-captured video from the concert.

Chow was certainly dressed for the occasion as she donned a sparkly purple dress paired with cowboy boots. She enjoyed the event with her stepson Mike Layton, his wife Brett Tyron, and Chow's two grandkids, Phoebe and Chloe.
