She never did let go, Jack.
It warmed our hearts to hear that when Kate Winslet tied the knot with Ned Rocknroll earlier in December, her Titanic co-star Leonardo DiCaprio walked her down the aisle.
Sure, celebs often attend each others' weddings; they even participate in regular people's nuptials, too. But we wondered which other celebs involved their celebrity friends in their weddings, like Winslet and DiCaprio.
Below, 11 other celebrities who asked their co-stars to be a part of their Big Day.

Perhaps Zach Braff and Donald Faison's bromance on "Scrubs" is so believable because the two are real-life buds. Braff <a href="http://www.huffingtonpost.com/2012/12/16/donald-faison-cacee-cobb-married-tie-the-knot-photos_n_2311174.html">hosted Faison's 2012 wedding </a>at his home in Los Angeles.
