Tyler And Braff 'Not Dating'

The pair was linked by a recent tabloid report that suggested they had enjoyed a cosy date in a Los Angeles wine bar.

A source alleged, "Zach had his arm wrapped around her and was whispering in her ear."

But Tyler's publicist insists the meeting was purely business, telling People magazine, "They are not dating. They were meeting about a film that Zach is directing."

The Armageddon actress has been single since splitting from her husband of five years, Royston Langdon, last year (08).
