Jennifer Aniston is allegedly harbouring a crush for the "Psycho" star Vince Vaughn, the New York Post reports.

The former "Friends" star and winner of the recent ShoWest female star of the year award, was reportedly thrilled when it was announced that she was chosen to do a movie with Vaughn.

The Post quoted a source as saying: "(Jennifer) has a major crush on Vince...and they have a lot of chemistry together."

Vaughn's representative has, however, denied the rumour saying, "They have a professional relationship".

Aniston announced her split with actor Brad Pitt in January. The "Troy" star has since then been dogged by rumours that he's romancing screen beauty Angelina Jolie and model April Florio.
