When he said he was "Sorry", he meant he should be forgiven and he would change for the good.

The singer has reportedly donated a whopping $10,000 to the music program at the Tulsa's Central High School in Oklahoma.  The superstar also performed an acoustic set for students during his Thursday’s surprise visit to the school.

The Biebs’ generous donation and acoustic show took place just a few hours before he performed at his 'Purpose World Tour' concert at Tulsa’s Bok Center on Thursday night, April 7.

During his Tulsa appearance, the Canandian singer hinted on Twitter, Thursday morning, "Something special in Tulsa today. #giveback.”

Tulsa Public Schools spokesman Chris Payne told FOX23 that Bieber dropped by the choir practice at Central High School in the afternoon and chatted with about 25 students. The 22-year-old pop star played two songs, accompanying himself on acoustic guitar.

The performance will air during the 2016 Radio Disney Music Awards which airs on May 1. Justin also listened to the choir sing and took selfies with the “totally shocked” students who “didn’t know he was coming,” Payne said.

Payne said Bieber made a verbal $10,000 donation to the school’s music program. The superstar’s pledge comes amid cuts to monies for Tulsa schools, reports The Inquisitr.
