Charlize Theron and Sean Penn are continuing to spend time together after they headed to Hawaii over the holidays.

The stars have been spotted leaving Theron’s home in LA then later returning to the ritzy Hollywood Hills address where Penn spent the night, E! News reports.

The site further says that the duo then, “emerged together Friday, with Theron behind the wheel of her black Lexus and Sean in the passenger seat, as they headed out for an hour-long drive to Penn’s Malibu home, where they spent the remainder of the day.”

Over at Penn’s place, he went jogging while she stayed home to relax with his dog.

The actors also hit an LA Starbucks together, but have both declined to comment on the nature of their seemingly cozy relationship.
