Heaton, who is currently pregnant with her first child, recently joined Price at the world premiere of Paranormal Activity 3, which saw them enter the Big Brother house for a brief period.
Andre recently claimed that he sometimes believes Price wants to get back together, but insisted that he has "no unfinished business" from their four-year marriage.
