Drew Barrymore has raised speculation that she is expecting her first baby.

The actress was seen leaving a doctor's office in Beverly Hills with fianc Will Kopelman last week holding what looked to be sonogram results.

TMZ reports that Drew's representative had "no comment" when asked if there was an impending arrival but no denial was given.

The Charlie's Angels star got engaged to her 34-year-old art consultant beau in December last year and sources say it is the "happiest" she has been in her whole life.

"There were sparks right away," a source told People magazine. "They just knew."

Although the pair have not yet wed, Drew is already settling into the role of Will's wife.

"She's still Drew, but she has calmed down," the source explained. "It's almost like they're already married.
