Bristol Palin

Bristol Palin has found herself in hot water again — this time after her 3-year-old son, Tripp, was shown mouthing off to his Aunt Willow on Bristol's reality show, Life's a Tripp.

"Go away you f-----!" the toddler says to his aunt, as Willow and Bristol cover their mouths in horror. "I don't like you."

"I've done a terrible job disciplining Tripp," Palin admits on the show. "I know he's going to continue to push the boundaries."

The question is, which F word did he use? Lifetime, which airs the show, partially bleeped out the word when the episode was broadcast, but The Huffington Post reported that the word Tripp used was a gay slur — an accusation his mother denies.

"He does NOT use slurs," Palin wrote on her blog in response to the report. "Let me be clear.  I'm not proud of what he did say.  Sadly, he used a different 'f word.'"

"Tripp is always surrounded by adults," she continued. "He's apparently picked up some language that I'd prefer he not use. On national television or at home."

It's not the first time Palin has come under fire in relation to alleged anti-gay comments on her show. But she insists Tripp's outburst had nothing to do with her own personal beliefs.

"I do oppose gay marriage," she wrote in her blog post. "I guess the temptation to label my three year old son is just too great for the lefty papers to resist."
