Here comes the bride… all dressed in Dior! Jennifer Lawrence is excitedly planning her wedding to director and boyfriend Darren Aronofsky — and the Oscar-winning actress already has one detail finalized.

Sources reveal exclusively to Life & Style that when it comes to her wedding dress, Jennifer, 27, has the perfect style in mind. "She wants to wear a custom-made Dior wedding dress, similar to the gown she wore to the Academy Awards," says a source. "Jen has joked to pals that she'll be extra careful not to fall down the aisle."

A designer gown would be perfect for the big day, especially since Jennifer and Darren, 48, are eying the rtizy Peninsula hotel in NYC for the "I do"s. However, guests, including Adele, Amy Schumer, and Bradley Cooper, can expect the reception to be just as laid-back as the Hunger Games star. "She wants her wedding party to be lots of fun, the source adds. "Champagne will be flowing throughout the evening, and she's even planning to have a karaoke station where she'll get to sing along to her favorite tunes with her pals."

Jennifer made her first red carpet appearance with the famed director earlier this month, and she can't stop gushing about her boyfriend of one year. “He told me his ideas and I thought they were brilliant and unique and challenging," she said at the Toronto Film Festival of their film Mother!. "I’ve been a fan of his for years — I think he’s bold and brave, and I think I said brilliant.”

In another interview with Vogue she revealed she has never been more certain about a relationship in her life. "We had energy. I had energy for him. I don’t know how he felt about me," she said. "I’ve been in relationships before where I am just confused. And I’m never confused with him.” Congrats to the happy couple!
