Rowland was singing her number one hit When Love Takes Over
Singer Kelly Rowland demanded an apology from Mobo awards organisers after claiming her performance was affected by poor sound quality.
The 28-year-old sang her hit single When Love Takes Over with David Guetta at Wednesday's event in Glasgow.
As she began, the star look unhappy and briefly stopped, later posting on Twitter she was "livid" at show bosses.
However, a Mobo spokesman claimed Rowland reviewed her performance after finishing and was "completely happy".
On her Twitter feed, the star had said: "I wanted you guys to be the 1st [sic] to hear it from me!
"Rehearsals. were fine. soundcheck. was fine. performance, was a struggle at 1st."
She said the poor sound had made her "work harder" and added: "What I will say is the Mobos owe me an apology! I was LIVID after the show!"
The former Destiny's Child singer said: "I got through it. It happens! The next show will be Better. TRUST!"
A Mobo spokesman said: "Kelly Rowland looked at the BBC's iPlayer and thought her performance was better than she initially thought when she came off stage and is completely happy with her performance."
Rowland and Guetta's song topped the UK chart in June.
