Don't hold your breath for a Fashion Police reunion any time soon, as the war of words between Giuliana Rancic and Kelly Osbourne continues to heat up.

A day after Osbourne described her former Fashion Police co-host as not "a good person," a source close to Rancic tells Peoplethat she finds Osbourne's comments "pathetic."

"She's not going to let Kelly's comments bother her," the source tells People. "She thinks Kelly should find something or someone else to obsess over."

The bad blood between Osbourne and Rancic dates back to March, when Rancic was criticized for comments she made about Zendaya's hair. Osbourne was one of Rancic's loudest detractors, and eventually quit Fashion Police.

The biggest celebrity feuds

Rancic's friend speculates that Osbourne's recent comments about Rancic were an attempt to "divert attention away from" the comments Osbourne recently made about Latinos on The View.
