After Leona Lewis confirmed her guest appearance on the show’s finale, she was rumoured to sing a duet with Che Chesterman. According to Huffington Post UK, there’s a high possibility that the two will collaborate.

Speaking to “Good Morning Britain,” Leona Lewis announced her appearance on “X Factor” finals this weekend. The “Bleeding Love” singer even hinted to perform a duet on the show.

“They asked me a couple of weeks ago… it’s a bit of a surprise actually, because it’s not just me,” Leona admitted. And because judge Rita Ora has confirmed to sing with her mentee, it looks like the arrow’s pointing to a Leona and Che collaboration.

But what about Reggie ‘N Bollie? The site reported that “X Factor” runner-up Fleur East expressed her willingness to team up with the group.

In a recent interview with Digital Spy, Fleur admitted that she would love to perform with Reggie ‘N Bollie. She referred to the boys as “hard-working” and “lovely.”

When asked about a possible duet, the singer said, “Yes! I’d be all over that. I’d be like, ‘Let’s do the Azonto together!’ Yeah, let’s do it.” Despite Fleur’s eagerness, reports have not yet confirmed their collaboration.

Meanwhile, Telly Mix reported that Rita Ora and Louisa Johnson still need to decide on their song choice. Speaking to The Sun, Rita mentioned that they want to find the right song.

“We want this performance to be about celebrating how far she has come and to get people to vote,” Rita said.

Likewise, crowd favourite Louisa Johnson is excited to perform alongside her mentor. Louisa admitted that it was a “big surprise” for her. Despite the excitement, the 17-year-old admitted that they’re still working on their song choice.
