Jessie J came out on top at the 2011 MOBO Awards on Wednesday, taking home four out of the five honors for which she was nominated.

The 23-year-old singer scored Best Album for her debut, 'Who You Are,' Best Song for her single 'Do It Like a Dude,' Best Newcomer and Best UK Act. The only category she lost out in was Best Video, which was awarded to Tinchy Stryder and Dappy's 'Spaceship.' The awards were determined by fan voting.

"Wow. I did not expect to win that at all," the British songbird said during her acceptance speech. "I just want to say the biggest thank you to my fans because I watched this last year by myself in my living room and no one knew who I was and now I just won best album. That is epic."

Adele and Rihanna were also celebrated at the Glasgow event with the 23-year-old songstress scoring Best R&B/Soul Act and the 'We Found Love' singer winning Best International Act. Jason Derulo nailed hosting duties during the awards show, which also included a tribute to Amy Winehouse that featured her 15-year-old goddaughter, Dionne Bromfield, performing 'Love Is a Losing Game.'
