Kate Upton has revealed her fiance Justin Verlander's pre and post-game sex rules.

The 24-year-old beauty happily - or perhaps unhappily - shared with Andy Cohen On Watch What Happens Live on Wednesday night that the Detroit Tigers pitcher puts their sex life in lock down around game time.

Loving lock down: Kate Upton has revealed her fiance Justin Verlander's pre and post-game sex rules on Watch What Happens Live on Wednesday night

After a fan rang in and rather awkwardly asked about whether her fiance needs to abstain to get his head in the game, the model did not hold back.

Kate said: 'There's no sex before a game - absolutely none! Also what I've just found out is, if he plays too well, there's no sex after, either.'

Despite fellow guest Ricky Martin suggesting she just makes him that little bit more tired after his game, Kate ruled it out.

'He's exhausted. It's kind of a buzzkill for me.'

Andy, who is also a big baseball fan, quizzed the cover girl over what her fiance thought about her foul-mouth rant.

Kate said: 'I had to write it so fast because he wasn't even off TV yet and I was like ''I have to write it before he gets off and edits me.'''
