How Many Times Has Keira Knightley Worn Her Wedding Dress?

It's rare enough that celebrities ever step out in the same dress twice, but apparently Keira Knightley isn't shy about recycling her fashion — especially when it comes to her wedding dress!

The 28-year-old actress stepped out at the Serious Fun London Gala Tuesday night in a gorgeous light pink Chanel Haute Couture number, but it wasn't the first time we've seen it; the brunette beauty actually donned the lovely gown to marry her sweetheart, musician James Righton, in the South of France back in May.

But Keira's actually three times a lady when it comes to the frilly frock. After all, if you think wearing your wedding dress after you get hitched is awesome, how about wearing that same gown years before the big day? Like, say, back in 2008?

Check out this video to see how Keira accessorized the dress each time, and be sure to tune in to "omg! Insider" on TV tonight for all the latest in entertainment news.
