Bruce Jenner believes his wife Kris works ''too hard''.

The 'Keeping Up With the Kardashians' star- who appears in the show alongside his spouse, their kids Kendall and Kylie and his stepchildren Kim, Kourtney, Khloe and Rob - admits he and his partner do fight on occasions, mostly because she is busy so often.

Asked when the last time he argued was, he said: ''It was probably with my wife before I left to come to London for the Olympics.

''Probably about scheduling - everybody's schedule and her working too hard.''

However, one thing neither he nor his wife are prepared to do is house work, and he admits he has not changed a bed sheet in some time because they utilize the help of a maid.

He said: ''We've got our maid Cruz, we've had her for 25 years. She does all the bed changing and stuff like that - so I haven't done that in a long time!''

His house is so clean, he would even be prepared to eat off the floor.

He added to heat magazine: ''In my house the floors are always clean. My wife keeps the house spotless, so I'd have no problem just picking food up and eating it.''
