Drew Barrymore: Is She Pregnant?

After the recently engaged actress was spotted leaving a doctor's office with a sonogram in-hand over the weekend, seen in a photo posted on TMZ.com, some are wondering whether Barrymore, 36, is expecting her first baby with fiancé Will Kopelman.

The couple would like to become parents, a source close to them told WHO last month. "Drew is so motherly," the source said at the time. "Will would like to be a dad. Family is so important to him."

When asked by WHO if Barrymore was expecting, her rep had no comment.

Although there could be another explanation for the sonogram, starting a family has long been on Barrymore's mind. "I definitely feel the beginnings of a tick-tock," she told PEOPLE in 2006. "Whether I have children or adopt, whatever form a family comes in, I would absolutely love to have it."

In recent weeks, the actress has stepped out for public appearances in notably loose-fitting clothing, though her characteristic style has always been on the bohemian side. At a Feb. 18 party celebrating Marni's new line for H&M, the actress was asked if she had selected a wedding dress yet. Laughing, she told reporters, "Oh, gosh, I don't know! I've been trying to figure it out! All I know is that I want something tasteful, something timeless."

Barrymore first stepped out with Kopelman, an art consultant, last February.
