See -- even famous people get cheated on!
This is the story -- apparantly someone got a video of Britneys man dancing veeeeery close with another woman and sold it to the media (jerk).
Britney's Dad Jamie got a wind of the video and bought all the rights to it for A LOT of money. He then showed Britney and she got upset and said the relationship is definitely over. Sad. I love Britney! Thankfully her Dad was smart and got a hold if that video before it went viral!
Here is the Instagram video she posted about being sad ... and what cheers her up!
