The "Veronica Mars" star put her growing baby bump on display during a trip to the Byron & Tracey Salon on Thursday afternoon in Beverly Hills, Calif.
The blonde beauty looked cute and casual, rocking a denim embroidered shift dress, white sandals and a matching white fedora.
Bell and her hubby Dax Shephard are already parents to daughter Lincoln Bell Shepard, 1. The 33-year-old actress says this pregnancy is "exactly the same" as her first one.
"Lincoln was an easy pregnancy and an easy baby, so hopefully this one will follow the same path," she told People magazine.
As for what to call their next bundle of joy, Kristen says the expectant parents are "completely stumped" after falling in love with Lincoln's name for a boy or girl the last time around.
"It's hard to take focus off her and think about the second baby, even though the second baby is here and growing," she explained.
"Lincoln's like my television. I love being a mom and I love watching her explore the world and talk to me about things," she added. "It's mostly babbles, but she signs, and so we can communicate. I've never been so interested in anything in my entire life. I have heard parents say that when you have a second child, your love doesn't divide, it multiplies, so I have confidence that will happen."
"And then eventually, I'll explode," she joked.
We can't wait to see the new little one!
