Kelly Clarkson isn't going to let her pregnancy stop her from standing by her man: in the wake of the latest rumors that her husband, Brandon Blackstock, is cheating on her, she took to her Twitter to let her fans -- and critics -- know that she's standing by her man!

Radar Online is reporting that two women so far have come forward to confess that they are cheating with Blackstock, even while Clarkson is pregnant with the couple's first child. Blackstock also has two children, ages 12 and 7, from a previous marriage. Clarkson, however, isn't having it.

"Keep hearing random rumors of me & Brandon splitting or that's he's cheating on me. Stop with all the lying please," the former American Idol winner wrote on her Twitter feed Friday night. "False rumors don't bother me & Brandon but they do affect the lives of our 12 & 7 yr old. They're kids &don't get that people can print lies."

According to The Huffington Post, the two women have gone to the infamous website TheDirty.com to talk about their exploits with Clarkson's husband. The posts, however, have since been removed, leading some to speculate that either Clarkson and Blackstock have gotten their lawyers involved, or the two women were lying about their exploits in the first place and were just looking for the proverbial "15 minutes of fame."

Even Blackstock's ex-wife, Melissa Ashworth, spoke out in defense of the couple. "This is ridiculous ... this silliness. I have my two children [by Brandon] right here, who I love," she told RadarOnline.com. "I adore Kelly and Brandon as a couple, so if I say anything it's going to be positive."

Clarkson and Blackstock's first child is expected to arrive in the summer of 2014. We wish the couple the best of luck with their upcoming arrival!
