Kathie Lee Gifford and Hoda Kotb have been friends and co-hosts of "Today's" 10 a.m. hour for a long time, but there's allegedly a feud going on behind-the-scenes. For starters, the network is in the midst of a huge overhaul adding Megyn Kelly to the mix.

The former Fox News journalist will take over Al Roker and Tamron Hall's 9 a.m. hour of the morning news program in September. Add to all of that, Hoda adopted a baby daughter a few months ago and it has switched around her priorities.

"Today" co-hosts feuding?

A source tells Radar Online that Kathie Lee Gifford and Hoda Kotb aren't getting on well anymore.

In fact, they're said to hardly speak to each other off-camera anymore. The insider adds that things have "gotten so bad," that Hoda has "moved dressing rooms."

She's now in Tamron Hall's old dressing room on the first floor -- the same floor that Matt Lauer and Savannah Guthrie are on. Kathie Lee is supposedly upset about the arrangement because she now feels isolated on a separate floor. When they were together, the "Today" buddies always had their doors open and would go in and out of each other's dressing room frequently.

Gifford feels ostracized

Kathie Lee and Hoda don't do the things outside of work they used to, the source shares. They used to go out to dinner and enjoy drinks together, but now that Hoda is taking care of a child, it's harder to keep things they way they used to be when she had more freedom.

Although Kathie Lee understands what it's like being a new mother, she feels like Hoda is blowing her off.

Is Megyn Kelly the reason for the discord? The insider continues that Gifford doesn't like the way Kotb is "kissing up" to Megyn. A few months ago Kotb joked that looked forward to hanging out with Kelly and bringing out her "wild side" once she's had a few drinks.

Great on-screen chemistry

Kathie Lee Gifford and Hoda Kotb have been friends for years and have great on-screen chemistry. The co-hosts are doing a great job of maintaining a united front if any of this is true. Part of being a professional in show business is being able to fool people, after all. Is there a feud they're hiding?

Dynamics and friendships change in the celebrity world at lightning speed. It's possible that these women are hitting a rough patch professionally and personally? It's normal in any industry for co-workers who have a good relationship to have a hard time once in a while, and Kathie Lee Gifford and Hoda Kotb are no different.
