A young Bruce Springsteen fan got out of being late to class in the most rock ’n’ roll way possible — by getting a note signed by The Boss himself!

The 9-year-old devotee, Xabi Glovsky of Claremont, Calif., was at the singer’s sold-out show in Los Angeles Tuesday night with his dad, Scott Glovsky, when they caught the rocker’s eye with a homemade sign.

“Bruce, I will be late to school tomorrow. Please sign my note :),” their poster read.

And once the concert ended, that’s exactly what he did.

“Dear Ms. Jackson, Xabi has been out very late rocking & rolling. Please excuse him if he is tardy,” Springsteen scrawled on a piece of loose-leaf paper after he had security personnel escort the father-son duo backstage.

The New Jersey native had performed for nearly 3¹/₂ hours — playing 35 songs — before ending the marathon show and meeting with the pair outside his dressing room.

“Although there were many musicians and celebrities at the concert, we were the first people to see him after the show,” Scott told the Claremont Courier. “He asked him for the name of his teacher, and how he spelled his name. He then pulled out a piece of paper and a pen. As Xabi sat next to him on the couch, Bruce thoughtfully created this beautiful note.”

Scott, who has attended more than 100 Springsteen concerts in the last three decades, said the exchange was more than his son — or he — could have ever asked for.

“I have been singing Xabi to sleep with Bruce Springsteen songs since he was born,” he explained. “I imagine that idols rarely live up to your expectations. Bruce lived up to every expectation a 9-year-old boy could have — or a 48-year-old boy.”

It wasn’t the first time young Xabi had caught the eye of the “Born to Run” singer. In 2012, on his sixth birthday, he attended a Springsteen concert at the LA Sports Arena, where the singer spotted a sign the kid made that read, “Today I am six.”

“Bruce saw the sign, came over and waved to Xabi and sang to him for a short period,” Scott ­recalled.
