The former American Idol winner has previously spoken of her desire to have more children, but said she would wait until the end of her current tour.
She said: "I do America until October, and then Canada in October, so I think we're coming here [to the UK] in November.
"Hopefully, because I plan on being pregnant very soon after that, so hopefully I get here!"
The singer also acknowledged how hard it is to balance being a mother with having a successful pop career.
She said: "After tour I want to start (trying) for the next one. It's hard being a woman and wanting kids and fitting in your career."
