During the opening weekend of her Las Vegas show, the pop star put former 'N Sync band member Lance Bass on a leash, but fans were even more surprised when she put her boyfriend on one!
On New Year's Eve, when it came time for someone to be strapped into the harness, it was her main man who apparently drew the short straw.
Brit forced him down onto his hands and knees and put the studded harness on him before "walking" him around the stage.
We get that it's all part of the show, and he was obviously a good sport about it, but it seems sort of degrading, don't you think?
Would you have agreed to do that if you were David?
