A pregnant Kelly Clarkson fired back on Twitter at rumors that her husband Brandon Blackstock was cheating and had an affair.
Clarkson, the original "American Idol" winner from Texas who has a successful singing career, called the cheating rumors "lies." Blackstock, a talent manager, was accused of cheating with an unidentified woman on TheDirty.com earlier this month. The post has since been removed.

The woman told The Dirty on Dec. 2 that she had been getting "close" to Blackstock in the past five months.
"We haven't slept together, but we’ve been intimate in other ways," the woman said. "I really hope his wife keeps her eye on him because he's not the great man she thinks he is."
Clarkson blasted the rumors on Twitter Friday.
Blackstock took a little more humorous approach to the rumors on Dec. 4.
Melissa Ashworth, Blackstock's ex-wife who has two children by him, came to the defense of the couple.
"This is ridiculous … this silliness," Ashworth told RadarOnline.com last week. "I have my two children (by Brandon) right here, who I love. I adore Kelly and Brandon as a couple, so if I say anything it’s going to be positive."
Jerry Reed, a Blackstock family friend, accused Blackstock a few months ago of cheating "three or four times" on Ashworth before their divorce in early 2012.
Blackstock and Clarkson are expecting their first child together. They were married in October.
