Just-friends Rachel McAdams and Jake Gyllenhaal got down outside Pittsburgh recently, partying with the cast and crew of their upcoming boxing flick Southpaw at a pub in Indiana, Pennsylvania. "Rachel and Jake, along with the director and crew, were on the dance floor and mixing it up," an insider says, noting that about 60 cast and crew members attended the bash. When the dance floor got too crowded, McAdams and Gyllenhaal retreated to a private table and eventually left around 2 a.m. "They were still having fun," the insider notes, "but mostly just hung out and talked."
