The snap appeared to have been posted to Itu's Instagram account, but is no longer there.
The couple confirmed their relationship on social media earlier this year, after rumours that the footballer and Sbahle Mpisane had split.
Taking to Instagram Stories, Sphelele said the pair were not together when Itu was involved with Sbahle, but revealed that she and Itu had dated before.
When asked if wedding bells may be on the cards soon, she responded: “Once I'm stable. Definitely!”
