Vince Vaughn has proposed to Jennifer Aniston, his co-star in the movie "The Break-Up", during their recent trip to Paris to promote the movie, according to reports.

Aniston, the 37-year-old ex-wife of heartthrob Brad Pitt, said yes after Vaughn, 36, popped the question while down on one knee and is already making plans for the wedding, the Internet Movie Database website said Wednesday.

It added that Aniston -- who started dating Vaughn while pairing with him on the set of "The Break-Up" -- wanted to wait until all the fuss over Pitt and girlfriend

Angelina Jolie's new baby had died down before exchanging vows.

Vaughn and Aniston followed in the footsteps of Tom Cruise and Katie Holmes, who last year also got engaged in Paris while on visits to plug films they were in.
