The three musicians, alongside Clean Bandit - who will be gracing the stage to perform for the first time - and Chase & Status are among artists who will be playing at the annual awards ceremony, which will take place on November 4 at the SSE Hydro in Glasgow, Scotland.
The 'Seven Days' musician - who will go head to head for the title of Best Male and Best Song alongside 'Frisky' hitmaker - is excited to be returning to the star studded music bash after he performed there in 2000.
Speaking about the ceremony, he said: ''I first performed at the MOBO Awards 16 years ago and walked away with three awards that night. I'm back with new music and it's only right that I celebrate this by joining MOBO as they celebrate their 21st birthday.''
And Laura, who performed on the MOBOs in 2013 - is also ''thrilled'' to be asked back to belt out her recent hits.
She said: ''I'm so thrilled to be back in Glasgow performing on the MOBO Awards stage. The MOBOs are one of the few music events that have really championed and supported urban music from Gospel to Grime, so it's an honour to be taking part once again.''
