The pair were rushing so the Spider-Man star could get to his spin class with his girlfriend's mum, apparently.
The former child star met Holland while filming 2017's Spider-Man: Homecoming.
"I'm excited to bring a fresh energy to this story alongside Tom, and to welcome new audiences to the theatre."
The pair couldn't help but sing along as the iconic track played during the BNP Paribas Open.
The Emmy winner celebrated Holland in the sweetest way.
