Drew Barrymore & Justin Long @ Oprah

Cinema sweetheart Drew Barrymore is more in love than ever!

The 33-year-old actress definitely wore her happiness on her sleeve on Monday’s Oprah Winfrey show. Her #1 fan, 29-year-old boyfriend Justin Long, sat in the front row of the audience.

After Drew sat down, Oprah noticed a special glow emanating from Drew and asked why she smelled so good.

Drew giggled, “We’ve been traveling a lot together–it’s been great. We used the hotel shampoo.” (Justin’s hair was wet, too.)

When Oprah asked Justin what he liked about Drew, he said, “She smells great. She’s beautiful and funny–the most compassionate person I’ve ever met.”

Drew couldn’t contain herself and added, “I’ve found a best friend. It’s the best. At some point, as you decide who you want to be and the person you want to become and you grow up, you make different choices and changes in your life. This relationship is great–it’s healthy and productive and supportive and full of humor. All of our friends get along great, which is awesome because we travel together in packs. We’re having an excellent time and we’re very fortunate.”

By the end of the show, Drew donated made a million-dollar donation.
