But rather than fly off the handle straight away, she and Christen, the other girlfriend, concocted a plan to really teach him a lesson.
Whilst Christen admits that she was 'the side chick', the cheater had told her that she was the only girl he was seeing and she had had no idea about Chelsea.
The girls also say they discovered their now-ex had been sleeping with his hairdresser as well as them - and even suggested there were more girls.
To really make him pay, Chelsea and Christen went round to their boyfriend's place and waited for him whilst he was in the shower - and filmed his shocked reaction when he stepped out of the bathroom in a towel to see the both of them there.
Even better, Chelsea and Christen have become close friends. Losing a cheating boyfriendand gaining a bestie sounds like a pretty good deal to us!
