James Corden's Carpool Karaoke just peaked, and it's all thanks to Gwen Stefani. The "Used to Love You" singer made an appearance in Corden's car (if those seats could talk, amirite?), and after singing along to her biggest hits, they went ahead and picked up George Clooney and Julia Roberts. Let's just say these two were all kinds of excited to sing "Hollaback Girl."
Apologies in advance for going here, but this shit is bananas, B-A-N-A-N-A-S.
Also, shout out to James Corden for shamelessly quoting Notting Hill at Julia Roberts. She's just a girl, standing in front of a boy, asking him to love her, sob.
