What a surprise! Last week, fashion designer Marc Jacobs clearly caught his partner, candlemaker Char Defrancesco, off-guard when he proposed to him in a Chipotle, leading off with a flash mob dancing to Prince's "Kiss."

We know this because both Jacobs and Defrancesco posted a video of the proposal on Instagram, where, between their two accounts and in only five days, it has been watched, cumulatively, more than 260,000 times.

We also know that Defrancesco said yes and that the whole thing was adorable.

What we didn't know, until now, was why Jacobs picked, as his preferred proposal locale, a humble Chipotle, which, you know, has tasty burrito bowls and all, but is not exactly the engagement venue you'd expect from a world-famous fashion designer. I mean, couldn't he have at least picked somewhere where the guacamole doesn't cost extra?

Anyhow, now, thanks to WWD, we have our explanation.

"It's his favorite restaurant. We have an annual [tradition]," Jacobs told the fashion site, addressing why Chipotle was the perfect place for him to propose.

Every year the couple goes to Chipotle to celebrate Defrancesco's birthday, which was on April 4. To be fair, this year Jacobs tried to switch things up by choosing a more upscale dining establishment to pop the question, but an unwitting Defrancesco, who apparently likes to stick to his rituals, declined.

"I wanted to take him out for a romantic dinner on his birthday and he was like, 'No, I want to go to Chipotle,'" Jacobs told WWD. "So I knew I had to [propose] somewhere where he wouldn't suspect that I was going to do that. And then I organized a flash mob to be there, but he didn't know anything about that. So I was successful about that."

Turns out Jacobs, whose own 55th birthday was on April 9, wasn't the only one who successfully kept a surprise up his sleeve. On Saturday night, Defrancesco threw a surprise birthday party for his freshly minted fiancé, and this one was a full-on fabulous affair where a host of the couple's famous friends, including Bette Midler, Cindy Sherman, Naomi Campbell, Lil' Kim, Sofia Coppola and Debbie Harry (perched on a giant cake, singing happy birthday), were on hand to fete the fashion icon.

Apparently Jacobs thought he was planning another surprise party for Defrancesco, albeit a smaller one with only 10 people (family, a few friends and presumably no flash mob), only to arrive to a room packed tight as a burrito with pals.

Sweet surprises all around!
