Drew also flaunted her baby bump on the Fit Pregnancy's October-November issue in a short floral dress and opened up about her pregnancy.

"I'm feeling great. I am in the happy place. I was sick at exactly the same time as my first pregnancy: from 6 weeks to 16 weeks. I'm at 19 weeks now. So, I've been out of the woods for a couple weeks and feeling much better," Drew said.

She also said she's been working out a lot more adding, "I've been doing a lot of swimming and that's been giving me a lot of extra energy. I'm just getting out and I'm more active."

Drew and her husband Peter Lanfer announced in July that they are expecting their second child this December. They welcomed their son, Micah Emmanuel, in January 2012.

"Peter and I are delighted to announce our pregnancy," she told People magazine in a statement at the time. "We can't wait to introduce Micah to his little brother or sister."
