Brooke Mueller Returns to L.A. -- With the Kids

12/6/2011 2:00 AM PST

Charlie Sheen's ex-wife Brooke Mueller successfully managed to transport her kids from Aspen back home to L.A. all by herself ... just days after she was popped for cocaine possession.

Mueller -- along with Bob and Max -- touched down at an L.A. airport, where they were met by a team of handlers who helped the gang into a waiting vehicle.

Once the family returned to Brooke's home, a mystery man was seen entering the property, hiding his face in a blanket. 

The mystery man was most likely Charlie Sheen ... who has sworn to help out with the kids while Brooke deals with her legal and personal issues.
