(LOS ANGELES) -- Now that 11-year-old Jared Gilmore has decided to take a series regular role on ABC’s show Once Upon a Time, a replacement for his role as Don and Betty’s son, Bobby, in AMC's Mad Men must be found, and Gilmore wants to give that person some advice.
TVGuide.com reports that Gilmore wants to warn his replacement about working with January Jones, saying, “She’s not as approachable as the others. She’s really serious about what she does.”
But have no fear Mr. Replacement, because Gilmore added, “Everyone else is so nice.”
Gilmore's comments caught the attention of Mad Men star John Slattery, who tells E! Online Jones' reputation for stand-offishness is perception only.
"That's the character," says Slattery. "Betty Draper is an intimidating woman I suppose, if you were a seven-year-old boy [or] her son."
When asked if Jones was a diva, Slattery declared, "No, she's a sweetheart. We got lucky."
