Christina Aguilera has pregnancy cravings for ''blackened'' BBQ food.
The 'Fighter' singer is pregnant with her second child - her first with fiance Matthew Rutler - and can't get enough of over-grilled meaty treats.
A source told OK! magazine: ''The other day, she went nuts for a plate of blackened BBQ.
''She laughs about it, but she was also relieved when she found out this craving isn't all that strange.''
Around 25 per cent of women are said to suffer from cravings for non-nutritious things, such as charred food, which contains lots of carbon.
It has been suggested this can be caused by a mineral deficiency, although there is no conclusive evidence.
Aside from her cravings, the 33-year-old star says her pregnancy with a sister to Max, six, is going smoothly.
She recently wrote on Twitter: ''So blissful in taking this time for creating all things blossoming new on the horizon... album, baby & beautiful music to come.''
Christina announced she was expecting in February, a week after Matthew proposed in the backyard of their new home in Los Angeles, which is still under construction, on Valentine's Day (14.02.14).
Christina was said to be completely ''shocked'' by the sunset proposal, for which Matthew wore a suit and filled a gazebo with candles and red roses.
