Johnny Depp movie set western

Johnny Depp isn't letting his split from longtime love Vanessa Paradis get in the way of his acting career. The 49-year-old actor is hard at work on the Colorado set of The Lone Ranger.

In the movie, filming deep in the Rocky Mountains, Depp plays Tonto ... The Lone Ranger's Native American partner.

Aside from rumors that Depp has been getting close to his 26-year-old Rum Diary co-star Amber Heard, RadarOnline reports that the newly single actor is romancing his publicist, Robin Baum(pictured below).

A source tells the site:

    "Robin is twice divorced and a mom but she and Johnny really seem to have some kind of crazy connection that goes way beyond a professional level. They travel a lot together for work and get to spend a lot of time together and they definitely have a total flirty vibe between them. I would put money on them having more than just a friendly relationship."

Depp and Paradis called it quits after 14 years together. The couple have two kids together ... 9-year-old Jack and 13-year-old Lily-Rose.
