‘Mad Men’ star January Jones seems to be developing quite a reputation for herself. First, Zach Galifianakis slammed Jones in an interview for being rude to him at a party.

And now, 11-year-old Jared Gilmore, who played Bobby Draper on the AMC drama, described Jones as unapproachable compared to the rest of his ‘Mad Men’ co-stars.

“Be careful around January [Jones],” he said. “She’s not as approachable as the others. She’s really serious about what she does. Everyone else is so nice.”

Gilmore’s comments won’t make for a tense work environment — he recently left ‘Mad Men’ to star in ABC’s ‘Once Upon a Time.’ While talking to TV Guide, Gilmore gave his replacement a warning about Jones.
