Gemma Oaten was "shocked" when she found out her new boyfriend had a secret fiancee.
The 'Holby City' actress is said to be "distraught" that her new lover Stuart Earp was still engaged to his partner Kerryann Clive, 23, while he was wining and dining her.
A friend told The Sun Online: "Poor Gemma has been distraught about people saying that she knew Stuart was still engaged after December last year.
"She firmly believed that the relationship had completely ended and that Stuart was a free agent. She was more shocked than anyone that this may not have been the case.
"Stuart insists that he was single and had remained friends with his ex.
"Gemma just wants to move on from the situation. She has some fantastic opportunities coming up and the rest of the year is looking very positive."
After the 33-year-old star's relationship with Stuart became public knowledge last week, Kerryann branded her now ex-partner a "liar" and accused him of "using" Gemma.
She said: "He is a liar, I am young, I have my whole life ahead of me. He has made the decision to do this. He is just focused on his career right now, that's all he cares about. I think he's using her to meet new people.
"Even when we split up on Sunday he was saying he loves me, saying he will love me until the day I die. He was saying all this stuff, while he was with her. It's just a bit sick really.
"I only found out last night when I got sent this link of them at the event, which was apparently on Friday. At that point we were still together. I ended it with him on Sunday because of how he has been and stuff. I had a feeling because he wasn't texting me that much and was always saying he was busy and so, I just thought it was best if we finished because his head was obviously somewhere else."
