Giuliana Who? Maria Menounos Feuding With Catt Sadler After Rancic's Exit, Report Claims

E! News anchor Maria Menounos, fresh off her feud with Giuliana Rancic, has a new rival in the network's correspondent Catt Sadler, RadarOnline.com has learned.

Menounos, 37, is leery of the 41-year-old beauty's climb up the ranks at the network, particularly after her grueling battle with Rancic.

"There was a big meeting to discuss how to use Catt more" at the network in terms of "better stories and better interviews," insiders told the NY Post.

The insider said that E! execs are "nervous about Maria," and unhappy with her recent work.

Due to what the insider said was a contractual stipulation from Menounos that she would inherit Rancic's job if she were to depart, execs are feeling "they've inherited her contract -- and regret it big-time."

Reps for the network and the anchor both denied the reports.

E! dubbed the report "completely inaccurate and absurd," stressing they're "thrilled with Maria's performance," and that "there is no 'battle' between Catt and Maria."
