Sophie Ellis-Bextor has apologised for being “cruel” to Robbie Williams after a clip of Ellis-Bextor resurfaced in Williams’ recent Netflix documentary.Addressing the clip in a new Instagram post today (November 12), Ellis-Bextor apologised to Williams and said she’d reached out to him “a few years back”, writing him a “note” apologising.Since then, Ellis-Bextor said the pair have become friends and she revealed they had even “made some songs together”.She wrote on Instagram: “In 1998, aged 19, I was very rude about @robbiewilliams and the clip of me being horrid is included in his brilliant Netflix documentary. I didn’t need to see it again to feel bad. I genuinely have felt crappy about how I spoke for the 25 years since I said it.“I thought it was clever to be gobby back then but it wasn’t cool then and it’s even worse to see it now.
