The two became engaged on New Year's Day during a holiday to the Maldives. However, it was reported last week that they had split following rows.
According to The Mirror, Crane has expressed hope that he and Harding will reunite, allegedly telling friends: "It's not over yet. We're just on a bit of a break.
"We were going through a rocky patch but when I come back from Ibiza we'll hopefully be able to get ourselves back on track."
Crane, who confirmed a "break" on Twitter, added: "We'll probably be back together in time for our wedding. Hopefully, none of our plans will change."
It was previously reported that neither Harding or Crane had plans to cancel their wedding venue, which is booked for next April.
