As it turns out, they are all really supportive, despite some people's trepidation that the lovebirds are moving too quickly.
"I'm very, very happy for them, I couldn't be more happy," France said. "I think if anybody finds like that's amazing."
When asked about the fact that Davidson and Grande had only been dating for a month when he popped the question, France said that, for some people, it just works out -- like for him and his husband, Rob.
"I told my husband five days into it that I would marry him, he said the same," France said. "And we're together 10 years later, so who knows?"
For Brown, the engagement was exciting news, and he was hoping to get some inside info, but his plans didn't work out.
"We all know them, and they're sweet, and I texted him immediately and was like, 'Hey! Did you get engaged? Oh my gosh, congratulations! I wanna send a gift!' But I was really being nosey and he didn't text me back," Brown said, disappointed.
Ultimately, it was Porowski who's quiet, sage wisdom summed up their defense of Davidson and Grande's engagement the best: "Sometimes, you just know."
"I just went shopping with him a couple days ago," France said, although he didn't reveal whether or not he'd be helping him shop for wedding clothes whenever that day comes.
