The actress showed off her bleached blonde buzz cut at a photo call for her new film "Miss You Already" in London on Thursday.
Collette looked gorgeous and confident as she posed for pics with costar Drew Barrymore at the event and sported a pink pin for Breast Cancer Awareness month.
The "Little Miss Sunshine" star shaved her head to play a cancer patient in the drama which follows two life-long gal pals whose friendship's put to the test when one becomes ill and the other begins a family, according to IMDb.
While we're guessing the new 'do is just a temporary look for the 41-year-old beauty, we think she can definitely rock the cut.
