Khloé Kardashian is getting married to boyfriend Tristan Thompson in just a few short months, and the 32-year-old has already decided on her wedding dress for the big day!

An insider tells Life & Style that the reality star wants to walk down the aisle in a fitted white custom Balmain gown paired with Louboutin heels. But before she can make that dream a reality, the former talk show host needs to keep her brother-in-law Kanye West from getting too involved.

The couple is sparing no expense on the nuptials, figuring they’ll make back whatever it costs with a contact from E! to televise the ceremony. “They’re willing to spend $2 million on a huge, extravagant event,” the insider shares. “[Momager] Kris [Jenner] got dollar signs in her eyes when Khloé told her the news. She was up all night typing a wedding plan and ideas for a TV special.”

In the end, Khloé is just happy to be marrying the love of her life. During a recent appearance on The Talk, the Strong Looks Better Naked author said, “I feel really happy and secure and I’m just in a really positive, healthy relationship.”

The Revenge Body star, who currently lives with her NBA player beau in Ohio, added, “I actually love Cleveland. Everyone is so nice there. I love the four seasons. I love that it snows… it’s a normal routine life. I love to cook, so I get to cook dinner every day. It’s this home, family thing that I’ve been craving that I get to have in Cleveland.”
