The small gesture prompted a number of fans to speculate whether or not the “In My Blood” singer, 20, was being flirty.
Before Baldwin was linked to Bieber, many believed she was involved with Mendes.

“No, we were not making our big debut,” the musician, whorecently releaseda self-titled album, told PEOPLE at the time. “Obviously Hailey and I are friends, and it was just really cool for me to be able to walk with her because she’s a vet and it was my first year, so it kind of took the pressure off a little bit.”
After news broke that Baldwin and Bieber got engaged, Mendes revealed he was one of thefirst to congratulatethe model.
“I texted Hailey the day of, and I said congrats,” Mendes said on the Australian showThe Project. “That’s what it is. I think everybody wants there to be more — there’s not.”
Bieber and Baldwingot marriedin September 2018 at a New York City courthouse.
Last month, the newlywedsopened up about their relationship, which is a constant work in progress, according to Baldwin.
“The thing is, marriage is very hard,” BaldwintoldVogue. “That is the sentence you should lead with. It’s really effing hard.”
The couple also revealed that they have been going to therapy to strengthen their communication and are working on making sure they can talk to each other without having their personalities clash.
“He’ll say, ‘I feel,’ and I’ll say, ‘I think,’ I have to really dive deep and struggle to be in touch with my emotions. He gets there immediately,” the model explained.

At the end of the day, all Baldwin wants is to have a stable bond with her husband — which doesn’t mean perfection but rather a foundation that’s built on always being there for each other through the ups and downs.
“It’s just that I’m fighting to do this the right way, to build a healthy relationship, I want people to know that,” she shared. “We’re coming from a really genuine place. But we’re two young people who are learning as we go. I’m not going to sit here and lie and say it’s all a magical fantasy. It’s always going to be hard. It’s a choice. You don’t feel it every single day. You don’t wake up every day saying, ‘I’m so absolutely so in love and you are perfect.’ That’s not what being married is.”
