So you think you're a pretty fly guy, eh, Ryan Phillippe? Not when you're walking around with your button-fly down!

Wearing an open-collar purple shirt and a wide-open pair of gray pants, the 35-year-old actor was spotted with his wardrobe malfunction on the set of his upcoming film "The Lincoln Lawyer," the Daily Mail reports.

In the movie, Phillippe plays a Beverly Hills playboy -- and judging by the near-fall-out-boy's trousers, wethinks maybe he's taking the role a little too seriously.

According to one report, Phillippe's crotch crisis was actually caught on film as he shot scenes for the legal drama. After realizing that he had left himself exposed, Phillippe buttoned up his bottoms, laughed off the incident, and got right back to work.

The following day on set, however, the ex-husband of Reese Witherspoon was flashing bulges of a different sort when he bared his impressive biceps in a tight white tank top. And yes, his pants were zipped.

Personally, we at StyleList think Phillippe's wardrobe malfunction is nothing to be embarrassed about. The scene in last May's comedy "MacGruber" in which he sports a celery stick where the sun don't shine? That's a whole 'nother story, folks!
