Chrissy Teigen says she doesn't take her modelling career ''very seriously.''

The Sports Illustrated beauty, who is set to judge MTV's new cooking competition 'Snack-Off,' also admits her outspoken posts on Twitter often get her in trouble with her agents at IMG.

The 28-year-old star, who is married to John Legend, told 'Late Night with Seth Meyers': ''My agency definitely is not so keen on it all the time. Well, just being a model you're not supposed to speak ever, really.''

She added: ''It's fun, but I don't take it very seriously. I am paid a good amount of money to not blink for 12 hours.''

Chrissy is excited to show off another side of her personality on her new reality TV show.

She said: ''Basically [it's] 'Top Chef; but for a little dirtier cuisine - hot pockets, hot dogs, oatmeal pies.''

The brunette beauty recently confessed she and 'All of Me' singer John aren't thinking about having children yet because they want to focus on work.

She said: ''We're not really thinking about it yet. Most of my friends have kids actually, and basically, nobody ever says, 'I wish I would have had them earlier!' So at this point, I'm having a lot of fun playing with my friends' babies.''
