Demi Lovato doesn't plan on going for a traditional look on her wedding day.

The "OK Not to Be OK" singer, 28, who got engaged to actor Max Ehrich in July, already has an idea of what she won't wear when she walks down the aisle.

"I have my image for what I would want it to [look like] if I got to do a big celebration. I don't wanna give it away but it's definitely not a white dress," Lovato told PopCrush.

Even though Lovato and Ehrich haven't decided whether they want to throw a big bash or just elope, the singer said she has started "looking at dresses." But she's mostly focused on making sure the actual wedding ceremony is as special as it can be. "I want to keep it sacred between me and him," Lovato said.

Lovato and Ehrich got engaged on July 22, less than four months after PEOPLE revealed they were dating. Ehrich, 29, asked the singer to marry him in Malibu, California, with a stunning diamond ring by celebrity jeweler Peter Marco.

After he popped the question, Lovato shared a series of photos from their beachside proposal on Instagram and opened up about saying "yes" to the man who made her want to "to be the best version" of herself.

"When I was a little girl, my birth dad always called me his 'little partner' — something that might've sounded strange without his southern cowboy like accent. To me it made perfect sense. And today that word makes perfect sense again but today I'm officially going to be someone else's partner," the singer wrote.

"@maxehrich - I knew I loved you the moment I met you," Lovato captioned the images. "It was something I can't describe to anyone who hasn’t experienced it firsthand but luckily you did too.. I've never felt so unconditionally loved by someone in my life (other than my parents) flaws and all."

"You never pressure me to be anything other than myself. And you make me want to be the best version of myself. I'm honored to accept your hand in marriage. I love you more than a caption could express but I'm ecstatic to start a family and life with you. I love you forever my baby. My partner. Here's to our future!!!! 😩😭❤️🥰😍."

Earlier this week, Lovato spoke with The Morning Mash Up on SiriusXM Hits 1 about her six-month-long relationship with Ehrich, and how quarantining together at the start of the coronavirus pandemic brought them closer.

"We were able to share this time together that we wouldn't have normally gotten to spend. And that accelerated our relationship on a level that you can't really explain to people, but quarantine either makes or breaks the deal," Lovato said. "And it really made that. So I'm really blessed, really fortunate and continuing to count my blessings every day."
