Spencer revealed this week following last Friday's final that he hadn't seen Khloe since filming finished almost two months ago.
He said: "We finished filming about six weeks ago and I haven't been able to see the winner since then."
A friend of Spencer's has also been reported as saying: "Spencer was looking forward to getting to know Khloe properly away from the cameras once they got back to Britain.
"However, when he saw photos of her all over Tom Pearce on the internet literally days after the wrap party, he was pretty shocked and surprised to say the least."
However Khloe hit back, saying that her relationship with Spencer was over before she hooked up with TOWIE star Tom.
Adding to rumours that Spencer was back with his Made In Chelsea ex Louise Thompson, Klhoe tweeted following last week's final: “All am saying #louiseandspencer goodnite :D”
She has since declared herself single, saying: “I don’t want anything to do with Spencer now – the show’s finished and that’s it. I’m single.
“I’m not interested in having a relationship with him. I’m just going to get on with my life.
“It was unbelievable to win, it felt amazing. But now we’re back to reality it doesn’t feel great.”
