Sophie Monk is top of the list as 2Day FM searches for a replacement for the departing Jackie O SOPHIE Monk has big shoes to fill if she takes over from Jackie O. But by the looks of her stilettos she might be taking the challenge literally. The singer, actor and radio host stepped out in this odd ensemble yesterday, photographed entering Southern Cross Austereo's Melbourne headquarters. Sophie Monk drops into Austero's Melbourne studios. Picture: Chris Scott Monk is reportedly a frontrunner to replace Jackie O on 2Day FM breakfast when she and Kyle Sandilands finish up at the end of the month. While contracts are yet to be signed, Jules Lund and Merrick Watts are understood to be the main contenders to round out the new-look breakfast show. Radio executives have trialled some major names for the plumb job, including Mel B. But Confidential understands Monk is top of the list, although they're concerned she may not stick with the job through turbulent times. "Sophie is distracted easily," says a well-placed source. The other major question is, will Sophie be relatable to the listeners of 2Day's Sydney audience. Sure, she's lived in Hollywood but can people relate to that day in and day out. While Lund is much loved, there's concern he will stay in Melbourne and co-host the Sydney show from there. Others have questioned Watts' appeal given his dismissal from Triple M drive and the fact he previously partnered with Tim Ross at Nova and went head-to-head with Kyle and Jackie O but failed. The industry has been rife with theories surrounding the major shake-up that will follow Kyle and Jackie O's departure from the network. There's been talk the pair will move to Mix 106.5 but new rumours suggest they could record a syndicated drive show through MCM.
