Is that really Sean Penn wearing lipstick?
It sure is. The two-time Oscar winning (and famously tough-guy) actor sported red lipstick and a wild, fuzzy mane while filming This Must Be The Place in Dublin, Ireland Monday, and RadarOnline.com has all the photos for you.
Penn teams up with famed Italian director Paolo Sorrentino for the drama, in which he plays a wealthy rock star on the hunt for the man who killed his father, an ex-Nazi war criminal living in the states.
It's been a summer of milestones for the movie star: the Milk star turned 50 last week, and his divorce to his wife of 14 years, actress Robin Wright, was finalized earlier this month.
The film, which co-stars Harry Dean Stanton and Frances McDormand, hits theaters next year.
