Capshaw recently spoke to PEOPLE about pregnancy the fourth time around.

“I’m [due] any minute now,” she said while attending the Annual H.E.A.R.T. Brunch. “I’m an ‘any-minuter.’ I’m the person that makes people very nervous! I’ve had more people offer to help me downstairs today than my whole life.”

The actress also shared that she was milking her precarious state as much as possible while she still could.

“I was with my girlfriend at a restaurant and we didn’t make a reservation and there was a wait for 30 minutes,” she said, adding that the manager offered them a table after just a minute of waiting.

“My girlfriend looks at me and is like, ‘Man, this whole Grey’s Anatomy thing totally pays off.’ ”

She added, “I was like, ‘Guess what! Don’t think that has anything to do with it!’ I’m a liability looking this pregnant, standing at the front of a restaurant waiting for a table. I have a couple more weeks to enjoy the front-of-the-line status.”
