NEW BOO???
It sure looks like Marcus Jordan's got a new woman in his life ... Michael's son was seen out with a pretty lady in France this week -- and their subtle PDA suggests they're certainly more than just friends.
Check out some videos Instagram model Ashley Stevenson posted to her social media page Wednesday night ... she and MJ were out at Bau0302oli Cannes getting awfully close.
The two sat next to each other at a table -- and at one point, she stroked his inner thigh while they grinned ear-to-ear for a camera.
