Douglas warned LaBeouf against dating Mulligan

London: Michael Douglas has revealed he warned his `Wall Street: Money Never Sleeps` co-stars Shia LaBeouf and Carey Mulligan against dating each other.

The veteran advised the young co-stars who recently ended their year-long romance against embarking on a relationship as it is never a good idea to mix business with pleasure, reports

"I warned Shia about that. I told him, `Do not get involved with your leading lady. Trust me. Whatever you do, don`t do that`," he said.
