The clip, which was captioned, “When you bump into your ex wife”, was also shared by Katya, who added a string of laughing emojis.
The light-hearted dig comes after the couple revealed they are in “no rush” to get a divorce.
“We’re good friends. Are we starting divorce proceedings? We haven’t got time right now,” she told OK! Magazine. “We’re in no rush.”
Neil turned up in full support of Katya as he attended her debut performance in The Wizard of Oz back in December.
