John Krasinski, Emily Blunt, Alison Brie and Jason Segel Sing Karaoke (VIDEO)

How would you like it if these actors crashed your party?!? The Office star John Krasinski and his actress wife Emily Blunt joined Community star Alison Brie and How I Met Your Mother actor Jason Segel for a night of karaoke during a bachelor party they weren’t exactly invited to, according to reports. 

John and Jason sang Joe Cocker’s “With a Little Help From My Friends,” the theme song for the coming of age ’80s show The Wonder Years. The boys got really into the music, taking full advantage of all the space on the stage. Meanwhile, the girls had their own time in the red spotlight.

Emily and Alison chose to sing Bonnie Tyler’s “Total Eclipse of the Heart.” Check out the video below!

Alison and Emily will be playing sisters in the upcoming movie Five-Year Engagement that will also star their karaoke companion Jason!
