The reality TV star told Heat that she had been in touch with her former Atomic Kitten bandmates Liz McClarnon and Natasha Hamilton.
Katona said: "I'd love to sing and perform again. I miss it. I texted Tash and Liz the other day and they invited me to see them in Blood Brothers, so yes, we're in touch."
However, McClarnon told the magazine that there were currently no plans for the 'Whole Again' group to reunite.
"I don't doubt that she misses performing," she said of Katona. "It is addictive, and she's good on stage. It's a shame she's out now, as she seemed to really enjoy it. I'm sure we'll cross paths again."
In 2009, it was claimed that Atomic Kitten could reunite as a four-piece, but nothing came of the reports.
