While many thought Hailey Baldwin and Justin Bieber have been keeping their wedding plans a secret, it turns out they’re just going with the flow. The model’s older sister, Alaia Baldwin, admitted she doesn’t even know what Hailey and her brother-in-law are planning. “We will see. Who knows what their plans are,” the 26-year-old told Us Weekly on May 8.

“They’re very up and down, so, I just … I’ll be there at some point in a dress, in sweats — we don’t know!” Alaia doesn’t seem to mind as she is supportive of their relationship and approves of Justin. “I appreciate that he is always his genuine self, and that’s what I’d say I like the most about him,” she told the outlet.

Considering the couple secretly married in a courthouse in September 2018, this is their chance to go all out. In January, a source told Us Weekly that Hailey and Justin are indecisive when it comes to how they want to celebrate. “They are still in the middle of deciding whether or not they want a big or small wedding,” the insider revealed at the time. “They would love a small wedding, but they have so many people that they want there and they know once they start planning, it could become bigger.”

Regardless of what they opt for, what matters is that they’re happy and that seems to be the case. “Hailey is so happy and Justin is doing great … He’s obviously still trying to focus on his mental health and staying in a good space, and that’s their main priority right now,” the insider added. Let’s not forget the amount of times the two gush over each other on social media. It’s obvious they are in love.

Despite their relationship not being perfect, they make it work. “You don’t wake up every day saying, ‘I’m absolutely so in love and you are perfect.'” Hailey told Vogue in February. “That’s not what being married is. But there’s something beautiful about it anyway — about wanting to fight for something, commit to building with someone.” Aw, so sweet!
