The 'Crazy In Love' singer could duet with show favourite Ella Henderson on the live final, The Mirror reports.
Beyonce last appeared in the final with Alexandra Burke in 2008, which Burke went on to win.
However, a spokesperson for the show has refused to confirm the story.
This year's final will be held in Manchester on 8 and 9 December and the 'Strictly' final is a week later.
New mum Beyonce has recently teamed up with her husband Jay-Z to raise $4 million (£2.46 million) for US President Barack Obama's re-election campaign.
The hip-hop power couple hosted a fundraiser at Jay-Z's 40/40 club in New York last month and saw 100 ticket buyers charged $40,000 (£24,618) each to get in, reports the Washington Post.
And last week the Destiny's Child star left her husband speechless when she joined him on stage in the US.
The songstress, clad in a black leather top and skimpy shorts, joined her rapper hubby on stage for their hit 'Crazy In Love' at Brooklyn's Barclays Centre on 6 October, but he got so caught up in his wife's performance that he missed his rap cue, reported MTV.com.
"Oh s***, I should probably rap here," he quipped when he realised his mistake.
