Kelly Osbourne goes in on Giuliana Rancic.

It appears Kelly Osbourne has something to say about Giuliana Rancic's explanation on Monday of her widely slammed dreadlocks dig at 18-year-old actress Zendaya Coleman.

In an interview with the Today show, the 40-year-old longtime E! host blamed bad editing for the ill-received Fashion Police joke.

But according to a thinly veiled tweet by Kelly on the same day, that isn't so.

"Liars ALWAYS get caught!" she tweeted.

According to Us Weekly, Kelly's tweet was definitely aimed at Giuliana. "They're totally feuding," the magazine quotes a source. "Kelly cannot understand why Giuliana keeps talking about editing when there was a whole audience and crew who heard and saw otherwise!" another source adds. "Kelly thinks Giuliana should have just been truthful, apologized, and moved on."

Following the highly publicized drama on the E! show, Kelly left Fashion Police in late February. Giuliana admitted to HuffPost Live on Tuesday, that the two -- as well as former host Kathy Griffin, who also left the show shortly after -- aren't exactly on the best terms.

"I haven't talked to [Kelly or Kathy Griffin] since the incident," she said. "There's nothing good that can come of trying to speak for them, [or guess] what they meant by their comments."
