Newly single Julianne Hough and her "Vampire Diaries" star BFF Nina Dobrev like to french ... braid their hair on the beach.

In a scene straight out of a porn film --  minus all the nudity and sex -- the orange bikini babes engaged in an innocent three-way hair braiding session with a third adult female friend while bronzing their supple flesh on a public Miami beach.

This isn't how one usually gets twisted in South Beach.
