Most of us non-famous people spend our birthdays with a couple handfuls of people, on a good year. But James Corden, friend to all, does nothing low-key. He spent his 38th birthday eve with four friends and, oh, you know, 90,000 randoms. Coldplay invited their missing fifth member and Chris Martin’s former carpool karaoke chauffeur onstage at the Rose Bowl on Sunday to perform “Nothing Compares 2 U” for the night’s Prince tribute (as they’ve been doing all tour). This time, there were no cars or bikes required — just James & Co., a stage, and some birthday cake. Never before has a grown man been so overcome with glee as James Corden being sung “Happy Birthday” by a chorus of thousands.
