Chrissy Teigen and Tyra Banks are reportedly ''barely speaking'' on the set of their new show.

The 'America's Next Top Model' host and the Sports Illustrated Swimsuit model are jointly working on 'The FAB Life' but are said to be ''so different'' that they are just not getting on.

A source said: ''You never put two supermodels on the same show together. Especially when one's more than 10 years younger than the other.

''They are so different. Tyra thinks about everything. She thinks about what to say, down to when to move her arm. Chrissy is from the new school, where she says whatever she wants.''

On the show, Tyra - who is also executive producing - is said to be leading ''a panel of diverse lifestyle experts'' which includes Yahoo Style editor-in-chief Joe Zee, interior designer Lauren Makk and YouTube's Leah Ashley.

It is said that ABC asked Tyra to cast Chrissy as a ''social media expert''. However, the pair are unlikely to appear on the screen too much together.

A source said: ''Don't look for her and Chrissy to co-host many segments together''.

Meanwhile, another insider has claimed there's no ''drama'' between the two models.

They told the New York Post's Page Six column: ''If Tyra had a problem with Chrissy, she wouldn't be on the show. They're friends, there's no drama.''
