It would have been a hilarious way to spoof how filtered men can be in rom-coms, often not even finding flaws or annoyances in their girlfriend’s behaviors.
Just imagine Rebel Wilson (who usually has a beautiful voice) horribly singing Prince’s Kiss as Liam Hemsworth, who plays her “love interest,” lovingly sighs at her interrupting his phone call.
Okay, I can see how this would have been a good scene to spoof.
