Penn arrived shortly after the rapper-actress was booked by police on suspicion on driving under the influence. As we first reported this morning, Eve was arrested after crashing her Maserati into a center divider on Hollywood Blvd. We spotted Penn leaving in a taxi close to 4:00 AM.
Police sources tell TMZ, "He came to see how Eve was doing." No word yet if Sean and Eve had been out together before her car accident.
