"Sh*t happens," as Mariah Carey quipped, but it rarely happens to her.
The fallout continues from the star's technical difficulties during her performance on Dick Clark's New Year's Rockin' Eve with Ryan Seacrest on Saturday night, with a source telling ET that Carey is upset with host Seacrest for his lack of support during the incident as her team continues to slam Dick Clark Productions.
"She was so upset with Ryan she couldn't even bear to stand next to him when they were scheduled to at the ball drop and walked off," the source says. “Her team feels he should have come out on stage and helped her instead of leaving her to deal with it on stage by herself. It wasn't gentlemanly or professional."

Carey announced, "We can't hear," during her performance of "Emotions" on Saturday, before falling out of sync with the music on "We Belong Together." She eventually dropped her microphone and walked off stage while ABC cut away to screaming fans.
The singer took to Twitter later that night to address the snafu, writing simply, "Sh*t happens."
"Have a happy and healthy new year everybody! Here's to making more headlines in 2017," she added.

"There was a production issue. Technical difficulties. There unfortunately was nothing she could do to continue with the performance given the circumstances," Carey's reps told ET at the time.
"Mariah noticed something was wrong," Carey's manager, Stella Bulochnikov, told ET on Monday. "She told the stage manager. They changed the mic pack out twice for her inner ear. And they told her that the frequency was off but that it would be on when she got on the stage."
"I don't think Mariah was deliberately set up to fail but they had major technical glitches," Bulochnikov explained, claiming Dick Clark Productions "sabotaged" Carey. "Their decision not to cut to commercial or cut the performance out of the west coast feed is in a way sabotaging as they wanted a viral moment."

Dick Clark Productions issued a statement on Sunday, defending the production against allegations of deliberate sabotage.
"To suggest that Dick Clark Productions, as producer of music shows including the American Music Awards, Billboard Music Awards, New Year's Rockin' Eve and Academy of Country Music Awards, would ever intentionally compromise the success of any artist is defamatory, outrageous and frankly absurd," the statement read.
"In very rare instances there are of course technical errors that can occur with live television, however, an initial investigation has indicated that Dick Clark Productions had no involvement in the challenges associated with Ms. Carey's New Year's Eve performance," the statement continued. "We want to be clear that we have the utmost respect for Ms. Carey as an artist and acknowledge her tremendous accomplishments in the industry."

However, Bulochnikov is now firing back, claiming that the statement issued by Dick Clark Productions is simply "not true" in a statement to ET.
"[DCP producer] Mark Shimmel called immediately after the show and confirmed the inner ear piece didn't work. For them to deny it now is in direct contradiction to what he said and admitted on the phone," Bulochnikov says. "He asked us what we would like to be done about it, I said I'd like the West Coast feed cut. He said he'd call us back. He called me back and said they would not cut the West Coast feed. I asked why not and he said, 'We just can't.' He then asked if we could put out a joint statement. I told him [no]."
