If you’re in Montecito, CA this Saturday, June 2^nd, make sure to stop by Drew Barrymore’s wedding…right. But she seriously is saying “I Do” for the third time this weekend, E! News has confirmed.

Drew was cutting it close to the big day, getting fitted for her dress one last time, when she was spotted with her best gal pal, Cameron Diaz in Beverly Hills. An insider told Us Weekly, “Drew has been leaning on Cameron a lot.”

Being a Jill of all trades, this probably wasn’t due to a lack of responsibility, it was most likely because she is preggers and wanted to make sure she wasn’t an inch off on the measurements. You can tailor dresses the day of, but who wants that stress? Not a pregnant bride to be, that’s who.

This will be Drew’s third time down the aisle. Let’s hope that third times the charm. She married a LA bartender in 1994, and of course everyone remembers when she wedded “Bum Bum Song” singer, Tom Green.

Cameron should be one of the bridesmaids, we hope, since she knew about the marriage before her BFF. Drew’s fiancé, Will Kopelman, told Cameron he was going to ask for Drew’s hand in advance. I guess he was asking for her permission?

Saturday should be filled with a who’s who of attendees, but other than Cameron, it’s been confirmed that another longtime friend and business partner, Jimmy Fallon’s wife, Nancy Juvonen and the late night host are already in California for the big day.

Congrats to the happy couple and we can’t wait to see what she went to that final fitting for! Usually baby bumps aren’t the best wedding accessory, but Drew can pull it off.
