A surprise guest named, Grant, appeared on stage in a shark costume during a Katy Perry concert in Auckland, New Zealand, on August 21 to propose to his partner Steph. During Perry’s final show of her 2018 tour in Spark Arena, Grant stood on a stage in the center of the crowd, wearing one of Perry’s shark onesies. In footage taken from the event, Perry is seen inviting Steph onstage, saying she received an email from Grant days earlier. Grant becomes teary as he declares his love for Steph before pulling a ring from his pocket and dropping to one knee and asking her to marry him. She is seen nodding her head and embracing him as the audience cheers for the newly-engaged couple. Credit: Tina Plunkett via Storyful
