Justin Bieber reveals his pride at graduating high school with a perfect GPA

Heartthrob Justin Bieber has revealed that he was a very dedicated student during his school days and graduated with an impeccable record.

During a recent chat with Martha Stewart for Interview magazine, he was asked if he dropped out of school and surprised the American icon with his response: "I finished high school with a 4.0 GPA."

The GPA (Grade Point Average) is used in North America to measure a student's academic achievement and it is calculated on a 4.0 scale, with 4.0 being the highest (equivalent to an A grade).

The 'As Long As You Love Me' sensation also opened up about his upcoming new album, which he described as being "very personal": "The new album’s going really well. I'm working a lot with Skrillex and Diplo and this guy named Poo Bear, who's an incredible writer."

"We've just been getting our groove. You kind of go through a period where you're in there and nothing comes and nothing comes, and then, finally, it's like bang-bang-bang – you get them all in a row. I'm at a place where I'm really happy and I'm ready to share my music."
