January Jones Does Yoga, Gets Dissed By 11-Year-Old

January Jones is almost ready to pop, but that doesn't mean she's going to stop exercising!

The Mad Men star headed out to a yoga studio in Los Angeles' Studio Lake neighborhood Tuesday afternoon. January has been keeping in shape, doing prenatal yoga for months to get ready for the birth of her first child.

Just as January is getting ready for her little one to arrive, she just got a verbal smackdown from another kid - her TV son!

Jared Gilmore, the 11-year-old actor who plays Don and Betty Draper's son Bobby on Mad Men, is leaving the show to work on the new show Once Upon a Time. But before he leaves, he has some choice words for the actor who will replace him on the AMC hit. He told TV Guide:

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

Ouch!
