Are Bradley Cooper and Alana Haim starring in a film together?

Photos from the set of Paul Thomas Anderson's upcoming film have caused speculation that Bradley Cooper and Alana Haim are portraying Jon Peters and Barbra Streisand, with their outfits looking uncannily similar to that of Peters and Streisand.

The film project doesn't have much information yet, but is described as a coming-of-age story set in the San Fernando Valley during the 1970s, and has the working title 'Soggy Bottom'.
