CNN boss Jeff Zucker pushed Anchor Erin Burnett out of her own studio.

Why?

Because Zucker was holding a party for his old college pals.

The NY Daily News reports that Zucker, hosted a party for friends in the studio that was supposed to be used to shoot Erin Burnett's "OutFront."

Burnett's show was moved two floors down from its usual home so that the honcho could use the state-of-the-art studio to hold the shindig for the 30th anniversary reunion committee of his Harvard class.

While Zuckerreminisced with around 60 alums upstairs at the company's 58th Street headquarters, the production crew was making do with a space much smaller than their usual digs on the 5th floor.

"There's room for a desk, chair, anchor and camera," said a source, "The stage manager and producers were squeezed in."

"Erin had her makeup done of the 7th floor in a room next to her studio," added the insider, "She could see them prepare for the party while getting her hair done - then she had to go down to the 5th floor to do show live."

"Can you image watching event staff display name tags and get ready for the party?," laughed our insider, "The makeup room is literally feet away from her studio!"
