Kelly Clarkson 'slams infidelity rumours' about new husband Brandon Blackstock

KELLY Clarkson isn’t usually short of a few words, and it appears the singer may already be speaking out about rumors that her new husband, Brandon Blackstock, cheated on her.

A comment under Clarkson’s name was posted on a story on TheDirty.com about Blackstock’s rumored affair. (When asked about the post by RadarOnline.com, Clarkson’s rep refused to deny it was from her).

"This is absolutely absurd," the comment, posted by "Kelly Clarkson" said. "The woman who posted this fictitious [sic] rumor about my husband use [sic] to be my personal assistant until I terminated her for trying to steal from me.

"She even tried to impersonate me by soliciting funds using my name and created a ficticious [sic] website," the post continued. "This woman is just out for revenge."

Whether or not the commenter is truly Clarkson, they’re not the only person speaking out to slam reports of Blackstock’s infidelity.

Speaking to Radaronline.com, Blackstock’s ex-wife, Melissa Ashworth (with whom he has two kids), has called the rumors "silliness" and said, "I adore Kelly and Brandon as a couple, so if I say anything it's going to be positive."

When asked about the rumours, a rep for Clarkson told Radar, "We do not comment on our artists’ personal lives."

The cheating scandal comes at a difficult time for Clarkson, who has been struggling with severe moing sickness during her first pregnancy. She recently postponed an overseas promotional tour for her new Christmas album, claiming to be "incredibly ill," and, earlier this week, told host Carson Daly on the US edition of The Voice that she’s "been better" and is "looking forward to the second trimester".

Clarkson and Blackstock were married in Tennessee in October and announced they were expecting their first child on November 19.
