January Jones, who is pregnant with her first child, was recently thrown a beach baby shower by her girlfriends, including her "Mad Men" co-star Christina Hendricks.
Witnesses say that the group mingled on an oceanfront patio in Malibu, California on Saturday. People quoted as souce as saying that Jones was "in a happy and playful mood" and the women were laughing a lot and "seemed to be having a great time."
Jones, 33, has not revealed the identity of her baby's father. She told People magazine earlier in the month that she is due "in the early fall." She has been spotting attending prenatal yoga classes recently, but said she's been balancing the exercise with plenty of Dairy Queen.
"We don't have [Dairy Queen] in L.A., but I was just home visiting my family in the Midwest and I went, literally, every day," Jones told People. "I made my dad take me. Pregnant or not, I love Dairy Queen. I usually get a cherry-dipped cone or sometimes I go for a Blizzard and a chili dog if I'm really hungry."
Jones also said that the baby's gender will be a surprise and she is mulling over baby names, but doesn't want to go too eccentric.
"I'm having a hard time. I'm looking for boy and girl names obviously, because it's going to be a surprise for me," the actress said. "I love Cary Grant, I like Marilyn Monroe. That seems kind of like a celebrity thing to do, those weird names. I'm not really into that. I don't want to be too clich? about it."
Jones confirmed her pregnancy in April, months after she and "Saturday Night Live" cast member Jason Sudeikis broke up. In February, she told OnTheRedCarpet.com that she is "not dating anyone."
Jones, who recently starred in "X-Men: First Class," is known for her role as Betty Draper in the AMC drama series "Mad Men," which takes place in the 1960s and stars Jon Hamm as Don Draper, an advertising firm partner who was once married to her character. The fifth season is slated to debut in March 2012 and the show is set to air for at least two more seasons.
