On Tuesday, 11-year-old actor Jared Gilmore revealed he had to "be careful" around the 33-year-old actress, who played his cold and emotionally closed-off mother on the AMC hit. "She's not as approachable as the others. She's really serious about what she does," Gilmore said. "Everyone else is so nice."
According to another one of Jones' costars, actor John Slattery, the actress isn't as unfriendly as Gilmore described.
"Well, it's an intimidating character," Slattery, 49, told E! News. "I mean, that's the character. Betty Draper is an intimidating woman I suppose, if you were a 7-year-old boy [or] her son."
Currently pregnant with her first child (the father's identity has yet to be revealed), Slattery has "no doubts" Jones "will make a great mother" in real life.
