KEVIN'S BACK - ALRIGHT

OH MY GAWD!!! KEVIN RICHARDSON JOINED THE BACKSTREET BOYS ONSTAGE AT THEIR SHOW ON SUNDAY NIGHT!!!

Back in 2006, (37-year-old) KEVIN RICHARDSON left the BACKSTREET BOYS . . . because he wanted to "move on with the next chapter of his life." But on Sunday night . . . out of nowhere . . . he joined the Backstreet Boys onstage in Los Angeles . . . for a performance of the BSB CLASSIC, "Shape of My Heart". (--This just once again PROVES the age-old proverb: "You can take the boy out of the boy band . . . but you can never take the boy band out of the boy.") (--Or . . . maybe it was . . . "You can take the middle-aged man out of the boy band . . . but you can't take the desire for fame and money out of the middle-aged man.")

--Naturally, the crowd went DOG NUTS when Kevin came out on the stage. (--If you don't believe me, here's a fan-shot video documenting the insanity . . .)

--The person who posted the video on YouTube described the hysteria . . . saying, quote, "There was not a dry eye on the audience. We all bawled our eyes out. I couldn't believe right in front of my very eyes I was seeing this." (--If you're wondering . . . there's no indication that Kevin will be returning to the Backstreet Boys. The Los Angeles show was the last stop on their current tour.)
