Brittany Snow keeps it cool in a strapless black top as she makes her way out of her apartment building in Los Angeles on Thursday afternoon (August 13).

Before hopping into her car, the 23-year-old actress noticed a sticky note that was posted on her car window. The Post-It Note read, “I’m soooooooooo in love with you.” Was the note written by boyfriend Ryan Rottman.

After reading the note, Brittany stopped off to grab a cup of coffee and did a little shopping at Intermix on Robertson Boulevard before attending a meeting in Beverly Hills.

WHO DO YOU THINK the sticky note love letter is from?
