The Saturdays singer is expected to take Willoughby’s place while she fills in for Ant McPartlin on the reality show.
A source told the Sun: “As soon as bosses for This Morning learnt that Holly had accepted the role on I'm A Celebrity they drafted their wish list and Rochelle was at the top.
“Obviously, Holly's are big shoes to fill, but Rochelle has been impressing bosses with her down-to-earth nature and presenting skills for a while now.”
The insider added that Humes is “super excited” and sees the short-stint as a “huge career opportunity”.
Standard Online has contacted ITV for comment.

The TV star told how she feels like she has won a competition after confirming she will be McPartlin’s replacement.
She said she is “excited” to be the chosen presenter, but joked she is “scared of everything that moves”.
In a statement she said: “I couldn’t be more excited to have been asked to stand alongside Dec for the next jungle adventure.
“I love Ant and want to send him my best wishes and support for a continued recovery.”
