The model revealed even more about her relationship with Bieber in a new 73 Questions video

Just when we thought we learned everything about Hailey Baldwin and Justin Bieber‘s relationship from their extremely candid Vogue March cover story, Baldwin just spilled some more details about their wedding and engagement.

In a new video for Vogue‘s 73 Questions series, the model finally revealed a detail about her wedding dress that she’ll wear to the couple’s upcoming religious ceremony. (The two secretly exchanged vows at a civil courthouse ceremony in September but are planning a bigger celebration.)

“I can’t say much but I can say it’s kind of like an off white color,” she revealed.

According to a source, their wedding may take place in April or May. “Justin and Hailey both love tropical destinations. They are currently looking into options for a tropical wedding,” a Bieber source told PEOPLE.

In the new video, Baldwin revealed that “not a lot” of her day is spent wedding planning, adding, “which reminds me I should probably get on top of it.”

The two got engaged in July, just a few weeks after rekindling their relationship, during a trip to the Bahamas. Baldwin said they were “alone in the house just the two of us.” Calling the moment, “very special.”

Bieber popped the question with a massive oval engagement ring, which Baldwin says is the things she’s most frightened of losing.

In the video, she opened up about more fashion insights including the trend she hopes comes back (anklets) the item she’d never wear (suspenders) and discussed Bieber’s sense of style. She says the item she swipes from his closet most often are his socks and says she wouldn’t throw anything away from his closet, “I think he has great style.”

As far as modeling goes, she calls Gisele Bündchen the best model of all time and says the runway she’s dying to walk one day is Louis Vuitton, preferably set to the songs of Kanye West.
