Usher "Excited" To See The Fans At Summertime Ball 2012 - Audio
The 'OMG' star says he is looking forward to making his second appearance at Wembley Stadium.
Usher has told Capital that he is "really excited" about performing at the Summertime Ball 2012 because he has missed the fans since the last time he performed at the event.
The R&B superstar made an appearance at the event in 2010 and is looking forward to making his return to Wembley Stadium today (9th June).
"This will be my second time playing it so I'm really excited about it," he confessed. "I really missed all of the fans since the last time – and right on the eve of my new album 'Looking For Myself' – just kind of warming things back up."
The star earlier took to his Twitter account to reveal his thoughts on the day and admitted he found it difficult to sleep.
Usher will join the likes of Kelly Clarkson, Jessie J and Katy Perry at the music spectacular today.
