Justin Bieber, Selena Gomez Sing Karaoke, Smooch

Justin Bieber neglected to tell us that his summer plans included hitting up karaoke clubs with his lady love, Selena Gomez. The adorable twosome was spotted out in L.A. on Monday night doing just that.

TMZ got their hands on a video of the couple being absolutely charming at Lucky Strike, where they sang the Kid Rock and Sheryl Crow duet, "Picture."

They each sounded completely cute as they sang the tune, surrounded by on-lookers. As the song wrapped up, Justin made things even cuter by grabbing Selena and planting a big kiss on her. They reportedly left sometime before midnight.

The couple are just the latest A-listers partaking in the age-old ritual of public singing. Recently, Jason Segel, John Krasinski, Emily Blunt and "Community" star Allison Brie were all spotted out getting their karaoke on. Jason and John rocked out to the classic Joe Cocker (by way of The Beatles) tune "With a Little Help From My Friends," while the ladies kept it fun with "Total Eclipse of the Heart."

Listen, celebs of the world, next time you plan on hitting up a karaoke club and belting out some feel-good tunes, feel free to give us a call. We love public humiliation!
