The Irish presenter has fronted the ITV2 show for two years, but has not yet signed up for a third run.
However, she explained that things are "looking good" for a return to the programme later this year.
"I miss Australia - the last series of I'm A Celebrity was brilliant," she told The Sun. "I definitely want to go back this year and things are looking good at the moment.
"I saw Ant & Dec and the producers recently, and we were all reminiscing. Because you see the same people all the time out there it becomes like a family."
Paul Gascoigne was named as her number one jungle contestant, after he recently expressed an interest in joining the show's lineup.
"I've heard a few times that Gazza could be on the show so maybe he will," she said. "That will definitely get column inches, as I'm sure he'll be pretty controversial. I don't know how nice he'll be or how good at challenges, but I'd like to see him in there."
Whitmore also dismissed rumours that she may follow former host Caroline Flack by hosting The Xtra Factor, following Olly Murs's departure.
She said: "I get asked about X Factor quite a lot, but I just want to get back to Australia at the moment - I don't think I'm ready to give that up just yet.
"I saw Olly this week and I told him I'll be sad to see him leave, but he feels his music is doing so well that he can't [stay]. As far as I know Caroline is doing it again, which is good because she's brilliant at it."
Michael Owen and James 'Arg' Argent have been linked with a spot on the I'm a Celebrity lineup.
