The singer, 41, appeared on US TV last night and kept mum on rumours she is expecting twins.
But the star did reveal her secret craving, fruit, and lots of it.
'I'm just about fruit,' Mariah said,
'My taste bud situation is unparalleled.
'I don't know what it is, but I'm just about fruit for some reason.
'It has to be really good for me to like it.'
Although she wasn't giving anything away about the possibility of twins Mariah was open about her weight gain.
'My fingers obviously swelled a little bit,' she said.
'I can't even get this ring off if I tried.'
Mariah also revealed she and her husband Nick Cannon will skip their annual ski-trip to Aspen.
'I can't go there this year because of the altitude,' she said. 'We're figuring it out, looking at different options.'
