Alex Jones has made her debut on The One Show, with viewers quick to declare her a Christine Bleakley ‘clone’.

The Welsh host brushed off a wardrobe hitch to front the show in a 1960s-style mini-dress alongside new partner Jason Manford.

Stepping into Christine and Adrian Chiles’s shoes for the first time, Jason said the pair had brought name badges to introduce themselves to their new audience.

As the show began, the comedian declared: “It could go either way, I suppose. Otherwise, in half an hour’s time we will be escorted off the premises. But I have made name badges for everyone, because I presume people may not know who we are.”

Alex, 32, had admitted to pre-show nerves after she forgot to pack her essential ‘pull-in knickers’ when she travelled to London from Wales.

But it was her likeness to Christine Bleakley which got viewers talking.

Lisa Collins, from Leicestershire, wrote on Twitter: “Alex Jones on One Show looks like she’s been cloned from Christine Bleakley.”

Joanne Williams, from Chester, wrote on the website: “Alex Jones looks SO much like Christine Bleakley but that Welsh accent is strong, really have to listen! Great start!”

Sister Act star Whoopi Goldberg was the pair’s first guest on the show, which included a feature on car clamping and otters in Scotland.

Alex, 32, selected a dress for her eagerly-anticipated debut after looking through the show’s wardrobe on Friday. But she told Chris Evans’s Radio 2 breakfast show: “It’s the underwear that pulls you in a bit. In my rush to get to London yesterday I didn’t pack it, so that dress I cannot wear.”
