Robbie Williams and Gary Barlow lit up the Royal Albert Hall on Monday (1 June) as they reunited on stage for the first time in almost a decade.
The former Take That bandmates joined Lulu at her London concert to perform a rendition of "Relight My Fire," a song the trio covered in 1993, footage taken by Rob Brown shows.
Lulu was also joined on stage by Boy George and Australian Eurovision entrant Delta Goodrem.
Profits from Lulu's sold-out show were donated to her charitable trust, Lulu's Mental Health Trust.
