SHOCK! Holly Valance's Strictly partner Artem Chigvintsev has a fractured spine
Fellow professional dancer Brendan Cole, 35, who was booted out with 63-year-old singer Lulu at the weekend, has taken over from Artem.
'So @TheBrendan_Cole is stepping in 4 Art at training this week. Just taking it a day at a time. Art is at training also, choreographing us,' Tweets Holly, 28.
'It's the most sensible thing to do, & gives his back a much needed break. Brendan is great & we'll just get on with it til Art can return.'
Artem, 29, sustained the injury last Friday during rehearsals but continued to dance a successful energetic jive on Saturday night's live show.
Though it was first thought to be a strained muscle, he's now been diagnosed with a transverse process fracture to the lumbar spine - caused by rotation or extreme sideways bending.
'So between Art's fracture & my constant spasm we're a motley crew! But THE SHOW MUST GO ON!!! He's still bossing me round, but from a chair!' Holly Tweets.
'And he LOVES all your sweet messages, so thank you for sending them our/his way! XX.'
