Bachelor star Spencer Matthews still dating Louise Thompson?
Rebecca claimed: “I knew within hours of arriving that it was all a pack of lies, because Spencer was still involved with Louise.
"He was definitely not interested in finding a soulmate - although dating Louise didn’t hold him back when it came to hitting on the other girls.
“It was clear that other than a quick fling, he couldn’t have cared less about any of us.
“When he wasn’t eyeing us all up he just looked bored.”
When quizzed about his MIC co-star Louise on the show, Spencer insisted they had "history" but worked better as friends.
Rebecca, on the other hand, claims that Spencer arrived on the programme "tanned from a holiday with Louise".
Posh reality star Louise, who admitted she "tried to persuade him not to be in the programme", is even said to have stayed in Spencer's villa during filming.
Rebecca says the process, which sees 24 girls compete for Spencer’s attention, was “a joke”.
She fumed: “Everything you see is contrived. I didn’t last long because the production team ordered me to kiss Spencer and I refused.
“By then I had seen enough to know I didn’t want to be anywhere near him, let alone give him a kiss for the cameras. Other girls were more prepared to play ball.
“I went into The Bachelor expecting to have some fun with a nice single guy.
“In reality, the whole thing was a nightmare.”
Both Spencer and Channel 5 deny Rebecca's claims.
Spencer, 23, said last night: "I only had the pleasure of Rebecca’s company for two minutes in a speed date in the first programme.
"Even in that short space of time I couldn’t see a future for us.
"I’m really sorry if I hurt her feelings. None of my decisions on this programme has been made with any malice."
A Channel 5 spokesman insisted Louise was NOT with Spencer during filming in the South Of France.
He added: “All these claims are categorically untrue.
"Spencer has been nothing but a gentleman in his dealings with the girls and has been a delight to work with.
"We are very grateful for Rebecca’s contribution to the programme."
