Barely more than two weeks after her first child, Xander Dane Jones, was born on Sept. 13, the actress, 33, was seen out and about with him – and back in beautiful shape.
As for how her maternity might play out on the new season of the AMC hit, costar Jon Hamm, 40, told PEOPLE at this past weekend’s Rape Foundation Annual Brunch, hosted by the cast of Mad Men: “I’ll let you see that when you see it, but she is no longer pregnant. She has had a baby, and she’s very excited and happy and healthy. Both sides are very healthy and happy, which is very sweet.”
Regarding cast reaction to the birth, he says, “We’re just excited that she got through the whole situation healthy.”
Costar John Slattery, 49, who saw a baby photo, concurs, saying, “[Her son’s] beautiful. … She’s very sweet, very funny, and she’s in love with that boy.”
The Mad Men actress is co-starring with the hit TV Show’s Chris Colfer on his big-screen movie debut, Struck by Lightning.
Christina said she’d also love to appear alongside Chris on popular music show Glee, where she could show off her singing talents.
"I would love to be on Glee," she told E! Online. "I sing a bit."
Chris, 21, is famed for playing Kurt Hummel in Glee, but has recently being branching out into other projects. The star has turned his hand to writing and producing, with the coming-of age movie.
Christina was impressed with Chris’ multitude of talents.
"It makes you cry and laugh," she said of the upcoming comedy film. "It’s very clever. It’s very smart. He’s just amazing. This guy can do anything."
Christina plays April in the upcoming picture, which tells the story of a young man who is struck by lightning and killed. He recounts the way he blackmailed his fellow classmates into contributing to his literary magazine.
Christina had fun playing her character.
"She’s kind of a Goody Two-shoes," she explained. "She’s a little naïve and hoping for the best but a little judgey too, a little judgmental. So she gets some surprises along the way."
Exclusive: 'Mad Men' cast to host Rape Treatment Center brunch
The cast of “Mad Men” will celebrate a full week with their hands on another Emmy for outstanding drama series by giving back: The stylish gang will host a fundraiser for Santa Monica-UCLA Medical Center’s Rape Treatment Center this Sunday, at the Beverly Hills estate of magnate Ron Burkle.
The cause, which champions care for victims of rape and sexual abuse as well as prevention, will be represented by series creator Matthew Weiner and stars Jon Hamm, Christina Hendricks, Elisabeth Moss, John Slattery, Aaron Staton and Vincent Kartheiser.
Weiner was initially approached to participate by longtime RTC supporter Slattery, who plays agency honcho Roger Sterling on “Mad Men.”
"When John asks me to do something, I do it," Weiner told the Ministry.
Thankfully so, as the Rape Treatment Center encourages an open dialogue about rape, still one of the most underreported crimes in the country, according to RTC head Gail Abarbanel.
"Over the course of the RTC’s history, television story lines have been effective in changing attitudes," Abarbanel said. "Mad Men" has certainly tackled the issue, particularly with Hendricks’ character Joan Holloway, whose fiance forced himself on her in the show’s second season.
"It’s been very interesting because we’re really telling human stories. We don’t go out of our way to make political statements," Weiner said. "We’ve had a lot of sexual violence on the show. Unfortunately, in the most civilized countries, this happens. Telling the story about Joan was a part of that."
Indeed, as a period drama, “Mad Men” doesn’t shy from gender inequality in and out of the workplace.
The show “really has a connection to what we do and to the beginning of the rape center,” Abarbanel said. “What they portray in the ’60s is really what we confronted in the ’70s. All the attitudes in the treatment of women … attitudes about victims, some of them, still persist today.”
The RTC and the “Mad Men” gang will work toward changing that come Sunday.
