London, March 20 (IANS): Reality star James Lock was left red-faced when his girlfriend Danielle Armstrong ended their relationship on reality TV show "The Only Way Is Essex".

Lock was accused of cheating on his girlfriend Armstrong with former "Big Brother" contestant Sallie Axl, reports mirror.co.uk

Armstrong posted on Twitter: "She was the girl he slept with." Lock denied the claim writing: "I admit I've got myself in stupid situations socialising with girls like you!! But I have never cheated on my girlfriend."

Armstrong dumped Lock on the reality TV show saying: "I don't want to be with you, James. And you've f**ked it all up because of your behaviour."

Lock sticks to his words, insisting that he did not do anything wrong and has remained faithful to Armstrong.

"Obviously, I wanted to be with Danielle, she means everything to me but I can't understand where she's coming from. She's basically, like, shooting me down, she's giving me nowhere to go with it," said Lock to ITV.
