Italian singer Pausini told the BBC’s Carl Nasman that she’s “very excited” and “proud” to be performing alongside Williams and Scherzinger at the closing ceremony.
“When Robbie [Williams] invited me to sing with him, I felt goosebumps everywhere because Robbie’s one of my favorite singer, songwriter, and performer,” Pausini told the BBC.
The celebrity line-up will continue at half-time with performances by Madonna, Justin Bieber, Shakira and BTS.
Madonna, the best-selling female music artist of all time, is set to perform after the launch of her new album, Confessions II, which debuted at number one on the Billboard 200 chart in July.
Bieber also returned to the spotlight earlier this year, with his biggest live performance in four years at the Coachella music festival after cancelling his Justice world tour because of health issues.
