Drew Barrymore and Will Kopelman stopped by a home store in LA yesterday. Drew was sporting the darker hair that she debuted at LACMA's Art and Film Gala over the weekend. At the bash, Drew and Will hung out with pals Jennifer Aniston and Justin Theroux and mingled with other stars like Cameron Diaz. It was Drew's first official event since giving birth to her daughter, Olive, in September. She's been out and about in the weeks since, though, and was also seen grabbing lunch with Will and the baby last week. Drew is not only focusing on motherhood, but it looks like she's also working on a new project with news that she plans to launch a makeup line for Walmart early next year.
