The former Mis-Teeq star controversially replaced Arlene Phillips on the panel of the celebrity dancing competition this year.
When asked if she would return next year, Dixon told The Mirror: "I'd like to, but there's talk of me going to America to promote my album, so I'll take each day as it comes."
A show source said: "We're very keen to keep Alesha, especially given the fuss it caused.
"But she is super ambitious and she won't be committing to anything until next year, once she sees what else is on offer. Bosses will be on tenterhooks."
A BBC spokesman added that "nothing is confirmed" regarding the makeup of next year's panel.
Dixon released the Gary Barlow co-written single 'To Love Again' earlier this month.
