Drew Barrymore Quietly Ties the Knot: Report

June 3, 2012— -- Drew Barrymore got married this weekend to her art consultant fiance, Will Kopelman.

Barrymore and Kopelman tied the knot in a small, private ceremony on Barrymore's Montecito, Calif. estate, attended only by close family and friends, according to People magazine.

The wedding was reportedly designed by the same wedding planners who handled Reese Witherspoon's nuptials last year.

It was a "classic, simple, very pretty, garden-inspired wedding" officiated by a rabbi close to the Kopelman family, a source told People. Barrymore reportedly wore a Chanel dress -- she was recently spotted going for a fitting at a Chanel boutique in Los Angeles, and Kopelman's father is the company's former CEO.

Several other celebrities were in attendance for the celebration, including Jimmy Fallon, Busy Philipps, and Cameron Diaz. About 100 guests were also present at Friday night's rehearsal dinner at a "luxury win-country hotel," and received gifts of "olives, chocolate truffles, and bouquets of lavender" from the couple, People reported.

Barrymore's Private Life

For a person who's been hugely famous since she was 6-years-old, Barrymore has uncharacteristically clammed up about her personal life.

She's been in the public eye for most of her 37 years. Born into a legendary Hollywood family, Barrymore starred in her first film when she was just six years old, and wrote her autobiography when she was 14, after two stints in rehab.

Lately, though, she's kept mum about some of most important aspects of her life, including a wedding and a reported pregnancy. Since getting together more than a year ago, Barrymore and Kopelman have largely been holding their cards close, revealing little and rarely speaking publicly.

"For celebrities who have been open about relationships in the past, it's common for them to remain private when they feel they've found the real thing," E! senior news correspondent Melanie Bromley told ABC. "And especially in this case, Drew's fiancé has never really been in the public eye before, he doesn't court publicity, he just happened to fall in love with a famous woman."

The near-silence is impressive when it comes to another aspect of Barrymore's life that is pretty tough to keep secret: her pregnancy.

In the months before her wedding, she's been seen on red carpets and out on the town with a growing baby bump.

Sources have confirmed to E! news that Barrymore is, in fact, pregnant, and the rumors have been flying around for months. Still, she hasn't said a public word about it, and requests for comment from Barrymore's management were not returned.

Many celebrity moms-to-be are very open and public about becoming pregnant, being pregnant, giving birth, and their newborn children. Barrymore's keeping quiet though.

This would be her first child, which could be part of the reason she's being so private about the pregnancy.

"It's possible she doesn't want to jinx anything," Rachel Teitelbaum, Us Magazine Deputy News Editor told ABC News, "and is only speaking about it to close family and friends."

It's not clear how far along she is in the pregnancy, but Bromley says it was a factor in when they decided to get married.
