Vanessa Minnillo admits pregnancy hormones have turned her in to a ''bitch''.

The 31-year-old 'Wipeout' host is expecting her first child with husband Nick Lachey, and says he has already been on the receiving end of many a mood swing.

Asked if she has started using her condition to get her other half to run errands, she said: ''I'm not using them as excuses to make him do stuff, but I am using them as an excuse as to why I'm such a b-i-t-c-h sometimes!

''I'll snap and them I'm like, 'Oh honey, it's the baby'.''

But the proud father-to-be is taking it all in his stride and has even been reading the ''man version of the book'' in a bid to understand what his wife is going through.

Talking to VH1's 'Big Morning Buzz Live' she explained: ''I'm a little quicker to snap, but I'm also quicker to apologize. He has been a gem!

''I'm only five months in and he's like 'Oh, it gets worse', Like six, seven, eight, nine I'm apparently supposed to be a complete basket case!''
