Billie, 36, found fame on the hit reality series alongside her sister Sam Faiers, 35, but now heat has learned Sam is refusing to appear as a guest – and this shocking snub is causing tension. ‘Billie was nervous about doing the podcast, as she’s mostly shed her TOWIE image,’ says an insider. Both original TOWIE cast members, Sam starred in 11 series, leaving in 2014, while Billie lasted a further two years. And, when their comeback series Sister Act was axed last November after just one run, it sparked rumours of fresh tension between the siblings. They were so close once, but Billie worries they’re drifting further apart and that Sam doesn’t need her as much.’
