(Cover) - EN Showbiz - Jessie J is devastated she spelt Justin Bieber's name wrong on Twitter.

The British singer is a huge fan of the 17-year-old Canadian pop star. The pair are good friends, with Justin personally inviting the brunette star to the premiere of his movie Justin Bieber: Never Say Never.

Jessie is proud to call him a pal, and decided to write about him on social networking site Twitter. She accidentally included a typo in his name though, and has hinted his fans weren't happy.

"I love the Bieber I'm a proper Bieber Diva now! I spelled his name wrong on Twitter once I won't be doing that again in a hurry!" she laughed. "He's a cool guy, though. He's young and he just goes to show that hard work pays off. It wasn't that long ago that he was just playing drums in his living room."

Jessie, 23, bonded with Justin because they both put everything they have into their careers. She admits worrying she wouldn't make it at times, especially when her dream impacted her relationship with loved ones.

"There were times when I wasn't getting paid, I hadn't seen my friends in ages and I had no social life, and everyone misunderstood my music," she explained to Shout. "That's why I got so emotional at The BRITs [where she won the 2011 Critics Choice Award] I think it just hit me how hard I'd worked to get there." (C) Cover Media
