Ashton Kutcher and Mila Kunis are not in an exclusive relationship.

The former 'That '70s Show' stars have reportedly been dating but are also seeing other people. The Ted actress and the Two and a Half Men actor were spotted riding around Hollywood on Ashton's motorcycle on June 17. The screen stars were also spotted sharing meals several times during the spring and apparently took a three-day road trip getaway outside Los Angeles in late April - but are not an official couple.

"They're not exclusive, but they are hanging out and seeing where it's going," a source said.

For six years, 34-year-old Ashton was married to 49-year-old Demi Moore. At the same time 28-year-old Mila was in a long-term relationship with 31-year-old actor Macaulay Culkin. "They've been hot for each other for years. It stretches back to when they were friends on their show!" a second insider added.
