"America's Next Top Model" creator and host Tyra Banks, 41, and LL Cool J's "Lip Sync Battle" co-host Chrissy Teigen, 29, are reportedly feuding after the pilot for their upcoming show "The FAB Life," which was filmed in 2014.

"You never put two supermodels on the same show together especially when one's more than 10 years younger than the other," a TV insider told Page Six adding that Banks and Teigen were "barely speaking."

According to the insider, "The FAB Life" hosts are very different as the "ANTM" judge "thinks about everything" and "about what to say, down to when to move her arm" while the "Lip Sync Battle" host is "from the new school, where she says whatever she wants."

Another source said Banks and Teigen are not expected to co-host many segments together in the syndicated show is set to debut in the fall on ABC stations. The hosts reportedly have had a "marketing shoot" in Los Angeles.

On "The FAB Life," Banks will not only executive produce the show but also lead a panel of various lifestyle experts, which include YouTube star Leah Ashley, interior designer Lauren Makk and Yahoo Style Editor-in-Chief Joe Zee, who used to be an Elle creative director.

On June 14, Sunday, Teigen was spotted in Los Angeles at LAX Airport showing off her long legs while arriving on a flight, according to Just Jared.

A day before this, both Banks and Teigen took to Twitter to slam the rumors about their feud.

"@tyrabanks I am just excited I'm cool enough to be in on-set feuds now! We need to write passive aggressive raps about each other now," Teigen tweeted.

Banks replied with a tweet, "Ha! That's the crazy stuff the press comes up w/@chrissyteigen. I look 4ward 2the many fake stories about crazy fights between U&I, boo!"
