The actress, 33, flaunted her baby bump on the magazine'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."

The actress and Lanfer, who wed in 2002, welcomed their son, Micah Emmanuel, in January 2012. Drew said she and her husband are waiting to find out the sex of their second baby.

Season 11 of Grey's Anatomy premieres on Thursday, Sept. 25 at 8/7c on ABC.
