New York, Mar 17: When American singer-songwriter Kelly Clarkson boasted that she could “talk about anything”, she was not joking.

Clarkson, 26, revealed about her health and personal hygiene, and also said that she never lied.

“I’ll talk about anything!” the New York Daily News quoted her as saying.

“I do not lie. Ever. I will tell my girlfriend if she looks fat in her jeans,” she added.

The first ‘American Idol’ also revealed to Blender magazine her tendency to use her shower to go tinkle.

“Anyone who says they don''t is lying,” she said.

She also revealed that every time she blows her nose, she inspects the tissue to see what colour comes out.

“If you have a cold you have to check, to see how sick you are!” she explained.

The singer, however, chose to draw the line when she was asked about some of her bodily functions, especially a query about when she last had sex.

“I’m not telling you that. But mama didn''t raise no ho,” she added. (ANI)
