Actress Katie Holmes and Jamie Foxx have reportedly been spending a lot of time together for over a year, but it's nothing serious.

Sources don't expect Holmes to take things to the next level with Foxx, reports people.com.

"This is not some intense romance. Jamie and Katie are friends and have been for a long time. They are two adults who are attractive and single, and so apparently conclusions will be drawn. But contrary to those conclusions, they're not about to run off and make some serious commitment," the source said.

Another insider said that Holmes has been "often" spotted visiting Foxx at his nearby home. They are said to "spend hours together" at a time.

Neither Holmes's nor Foxx's representatives have commented on the rumours yet.
