The England international was expected to wed the Dancing On Ice host in the summer, but due to the player's uncertainty over his future, the wedding has been called off for the time being.
"She and Frank really want to get married, they have been engaged for nearly two years," a source told The People. "But they thought that as they have very little idea of where they could end up, the best thing was to cancel.
"They knew exactly what sort of wedding they wanted and everyone was looking forward to it but now it is just impossible. They will start thinking about it again when they know which club Frank will be playing at. Everything is so up in the air."
Recent reports have claimed that Lampard has been offered a deal to move to MLS side Los Angeles Galaxy.
