Amy Winehouse is set to make her TV comeback on Saturday on Strictly Come Dancing.
The BBC confirmed speculation that Winehouse will sing backing vocals for her 13-year-old god-daughter Dionne Bromfield in a live performance on the show.
The Grammy winner will provide backing vocals as Dionne performs her single Mama Said, taken from the forthcoming album Introducing Dionne Bromfield.
This weekend also sees another much-awaited comeback, as Robbie Williams performs his new single Bodies on The X Factor on Sunday.
The appearance on the show will mark the first time Robbie has performed in the UK since 2006.
BBC1's Strictly starts at 7pm and ends at 9.15pm, while The X Factor, which kicks off its live stages this weekend, is running a two-hour show on UTV from 8pm on Saturday.
Winehouse was quoted in the Radio Times as saying of Dionne, who is signed to the Rehab singer's own label, Lioness Records: "She's so much better than I was at her age. I'm so proud. She's my number one."
The troubled star, 26, made her return to live performing in Britain in August after an eight-month stay in the Caribbean.
She appeared on stage with ska band The Specials at the V Festival in Chelmsford.
Winehouse has struggled with drink and drug problems in recent years and was divorced by her estranged husband Blake Fielder-Civil in July on grounds of adultery.
Dionne said in a statement: "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."
