A source close to Kym told The Mirror at the time: "Kym is so happy with Sam and they couldn't contain their excitement so it felt natural to put pics on social media and tell the world about the relationship.
Kym had been starring as Cruella De Vil in the musical tour of 101 Dalmatians, which is where she met Samuel, who starred as Tom Dearly.
The couple were very open with their affection for one another, often sharing gushing tributes, with Kym saying she had met the "most amazing ever" back in August.
A source told The Sun: "Once Kym’s role in 101 Dalmatians ended it became harder to spend time together and some of the magic they had at the beginning just disappeared.
Hitting back at their critics, Sam wrote note on his Story as he shared: "Opinions are like a**eholes... everyone's got one, but they're still a**eholes."
