After a long hiatus from the spotlight, Amy Winehouse has announced she will perform on Strictly Come Dancing this weekend in support of her goddaughter, singer Dionne Bromfield.

The 13-year-old is due to release her first album, Introducing Dionne Bromfield, after Winehouse established a music label, Lioness Records, and signed the teenager from Kent.

She will perform her debut single, Mama Said, for Stictly’s huge Saturday night audience with her famous bee-hived godmother on backing vocals.

Today the teenager said: “Amy and I both love Strictly Come Dancing. I watch it every single Saturday, so it was brilliant to find out I’ll be on TV for the first time singing on one of my favourite shows.”

Mark Linsey, the BBC’s Controller of Entertainment Commissioning, said: "We are delighted to showcase the television debut of Dionne Bromfield on Strictly Come Dancing.

"Dionne is an exceptional new talent and it will be an extra special event for our viewers to see her perform alongside Amy Winehouse, an artist we have been looking to book on the show for some time."

Winehouse, who has been largely absent from the music while waging a long and very public battle with drug addiction, is not the only star stepping back into the spotlight on primetime TV this weekend: Robbie Williams is due to appear on both the Saturday and Sunday night episodes of ITV show The X Factor.

The former Take That singer turned solo chart-topper will mentor the contestants on Saturday night and perform the first single, Bodies, from his comeback album, Reality Killed the Video Star, on Sunday.

He has been in self-imposed exile from the music industry since his 2006 album Rudebox was slated by critics.

Sunday night's show will also feature last year’s winner Alexandra Burke, who is expected to perform her first single, Bad Boys.

But the glut of high-profile guest appearances is likely to reignite debate over the scheduling of Strictly and The X Factor.

The BBC has endured a wave of criticism after moving its popular dance show to a later Saturday night slot this year, putting it in competition with the high-rating ITV singing show.

Accused of “aggressive scheduling”, the BBC has refused to change the show's time slot but has suffered as a result - The X Factor has lured several million more viewers each week than its rival.
