Recent comments from himself and his wife Cat Deeley at the IFTA Awards were coy, but people have been eager to read between the lines and ramp up speculation.
"I've only really a couple of things to say on that I think the Late Late Show is one of the greatest TV shows on the planet, and whoever gets it is going to be really lucky," said his wife Cat Deeley.
"But I think something that maybe hasn't been said," added Kielty.
"I've done chat shows before, I know how difficult they are. I've been a guest on the Late Late Show, and I've sat alongside Ryan doing his stuff, and whoever gets that gig, they're going to have huge shoes to fill."
