Not too surprising to see Christine Bleakley and Emma Willis as the two name put forward this week as in the running to cover Holly - if reports are believe Phil favours the former but ITV favour Emma, although I suspect a combination of them both is quite likely to try and keep all parties happy. I think last time she was off Jenni Falconer officially shared stand in duties with Ruth.
Only because Jenni was heavily pregnant herself! Personally think it will be shared three ways between Bleakley, Willis and Ruth seeing as Emma has other duties, and will probably be filming the Voice series 4 (all being well) during the autumn.
