Can my nose be reshaped to look like megan fox's nose? (photo)

It looks like you could have steps taken that would alter your nose towards the shape Megan has.  Some tip cartilage refinement looks likely, and could be done with either an open or endonasal approach.  I would suggest endonasal.  However it also looks like Megan's nose is just a little longer than yours, where her tip is rotated a little lower.  There are a number of ways to do that as well, including a septal extension graft.  The key is to discuss that in person with a rhinoplasty surgeon.  That way imaging can be used to aid the conversation, and do the best visualization to see if aesthetics match.

The nose can be straightened, and the tip can be refined. An
exam would be necessary to provide an evaluation of what would be right
for you.  This may cost $6000 on the low end.Find a board certified plastic surgeon who performs hundreds
of rhinoplasties and rhinoplasty revisions each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA

Maybey, most likely, sure!!! Best to seek ONLY IN PERSON evaluations to determine exactly what is possible for you..
