Taylor Swift was joined by her friend and supporting act Gracie Abrams during the third night of her six-show Eras Tour run at Toronto's Rogers Centre on Saturday, Nov. 16. The pair performed a surprise mashup of Swift's '1989' track 'Out of the Woods' and their collaboration 'Us' from Abrams' 'The Secret of Us' album.

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