Selena Gomez, easily the hardest working 18-year-old in pop music, has just released a reworked version of the video for her "love yourself" anthem, 'Who Says.' The new version includes clips from her upcoming girls-on-a-road-trip film 'Monte Carlo,' which lands in multiplexes on July 1. Gomez's new album, 'When the Sun Goes Down,' is out June 28. So, she's a busy, busy girl.  No wonder she was hospitalized for malnourishment two weeks ago -- how does she find the time to eat?!

However, what better of a promotional vehicle for her new album than her new film and vice versa! This is a stroke of brilliant marketing as it reaches all facets of Gomez's fans.

In the new 'Who Says' video, we are treated to clips of Gomez and her 'Monte Carlo' girlfriends Katie Cassidy and Leighton Meester as they admire the Eiffel Tower, get their passports stamped, revel in their hotel accommodations, lie on the beach, wear expensive couture gowns and engage in other sorts of female bonding activities.

Gomez even appears in an intro to the new video, saying, "I hope you enjoyed it as much as I enjoyed making it." We did, we did. We can't wait to tag along with Gomez when she goes on her all-girl road trip and impersonates a British heiress in 'Monte Carlo.
