It appears that Tyra Banks’ truce with model Naomi Campbell is officially over.

According to insiders, the rivalry between Naomi Campbell and Tyra Banks has been back on since the debut of Naomi’s modeling competition show ‘The Face’ …

The National Enquirer reports:

TYRA BELIEVES NAOMI’S PROGRAM is a cheap rip-off of her own successful decade-long series, “America’s Next Top Model,” say sources.

Adding fuel to the fire, Naomi, 42, tapped Nigel Barker – a judge who was axed from Tyra’s show after 18 seasons – to host her new Oxygen Network competition.

“Tyra feels her rival is going for blood!” an insider told The ENQUIRER.

The 39-year-old beauty has plenty to be concerned about, say sources.

“America’s Next Top Model” has just been cut back from two seasons per year to one by the CW Network.

Meanwhile, Naomi’s show features a powerhouse line-up, including the runway superstar and fellow models Karolina Kurkova, 28, and Coco Rocha, 24, mentoring three teams of aspiring models competing to represent ULTA beauty products.
