Kelly Clarkson's food cravings

The 33-year-old singer - who has 14-month-old daughter River with husband Brandon Blackstock - is expecting her second child and pregnancy is making her experience strong desires for certain savoury foods.

She tweeted early this morning (10.09.15): "I want a giant plate of pickles, green olives, cheese, and crackers.....like right now. #preggerprobs (sic)" 

The 'Stronger' hitmaker announced her pregnancy on stage at Los Angeles' Staples Center last month, stopping during a performance of her track 'Piece By Piece' to share the news with her fans.

Kelly, who broke down in tears as she revealed her pregnancy, said: "I was not planning on announcing this. I'm totally pregnant!"

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."
