Kristen Bell admits her second pregnancy is ''five percent harder.''

The 'Veronica Mars' star, who already has daughter Lincoln, 15 months, with husband Dax Shepard, says she is more ''active'' these days because she is so busy chasing after their toddler.

Asked to compare both experiences, the 34-year-old actress told UsMagazine.com: ''It's been exactly the same. Maybe five percent harder because I chase a toddler, but at the same time, it keeps me active. But yeah, it's been identical.''

The blonde beauty is determined to have a healthy pregnancy and doesn't have any junk food cravings.

She said: ''I gave up refined sugar a couple of months ago. And that keeps my cravings low. I mean, I still crave food in general but I'm not like waking up with a starve, going, 'I need dark chocolate!' ''

Kristen recently confessed she didn't have a lot of time to focus on her unborn baby.

She said: ''It's hard to take focus off her [Lincoln] and think about the second baby, even though the second baby is here and growing.''

She added: ''Lincoln's like my television. I love being a mom and I love watching her explore the world and talk to me about things. 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.''
