ET takes a look back at how their love story evolved so quickly.
A source told ET on Tuesday that the lovebirds are expected to get married this weekend in India. But before the two officially say "I do," we're taking a trip down memory lane to see how their romance has blossomed over time.
Sept. 8, 2016: It Goes Down in the DM
Like many modern-day romances, Jonas first got Chopra's attention by sliding in her Twitter DMs! The singer told Vogue magazine he sent her a message that read, "I'm hearing from a few mutual friends that we should meet."
"She responded day of with a message that said, 'My team can read this. Why don't you just text me,'" Jonas recalled, revealing that the first few texts were "friendly with an eye toward flirtation."
"Boy got the number!" Chopra added.
Feb. 26, 2017: The Night They Met
In their Vogue tell-all, Chopra and Jonas personally share their love story for the first time, revealing they first met at last year's Vanity Fair Oscars party. Jonas said he stopped in his tracks as soon as he saw the Indian beauty walk by.
"I put my drink down, got on one knee — this is in front of a bunch of people — and I say, 'You’re real. Where have you been all my life?' Like, loud," he shared.
Following the party, Jonas and Chopra eventually met up for a proper drink in New York City, where the night ended at Chopra's apartment... with her mom. After they "hung out for a couple of hours," Chopra said Jonas "patted" her on the back before he left.
"There was no kiss. There was nothing. She's still upset about that," the "Chains" singer joked. "[Her] mom was in the house! I thought it was a respectful first night."
"It was too respectful if you ask me!" added Chopra.
April 30, 2017: First Public Pic
Jonas, 26, and Chopra, 36, first sparked romance rumors over a year ago after they posed together on the red carpet at the Met Gala due to the fact that they were both rocking ensembles by Ralph Lauren. While the two certainly looked good standing side by side, they reportedly said at the time that they were just friends.
Then, during an appearance on Watch What Happens Live With Andy Cohen, Chopra was asked whether there were "any flirtatious vibes" with Jonas at the party. "We didn't have time yet," she said about having the opportunity to get to know Jonas on a more personal level. "Maybe the next time we meet?"
May 29, 2018: Jonas and Chopra Spark Dating Rumors... Again!
After their Met Gala meet-up, the chances of Jonas and Chopra being a real-life couple seemed slim, as the two were not publicly seen together again and the rumors started to dwindle. But all that changed in May of this year, when they were spotted out and about together several times during Memorial Day weekend.
The duo kicked off their time together by catching Beauty and the Beast Live in Concert at the Hollywood Bowl in Los Angeles, followed by a Dodgers game a day later. An onlooker at the sporting event told ET at the time that Chopra and Jonas looked "very happy" and were "super smiley" together.
"They sat really close and were talking to each other a lot during the game," the onlooker added. "They didn't show any PDA. It was just the two of them and they definitely were acting very friendly, and couple-like."
Jonas told Vogue that the Dodgers game was their third date, and that's when he knew Chopra was the one.

"That smile," he wrote, adding a red heart emoji.
June 11, 2018: Meeting the Family
The rumor mill began buzzing again when Jonas invited Chopra as his +1 to his cousin's wedding in New Jersey. A source told ET at the time that the two were also getting ready to jet off to India together, where Jonas was expected to meet Chopra's mother, Madhu, for the first time.
June 22, 2018: Instagram Official
It's not the real deal until it's on social media, right? Following a few more public outings and date nights, it became clear to fans that Jonas and Chopra were definitely more than "just friends."

July 13, 2018: Chopra Talks Marriage With ET
When ET exclusively caught up with Chopra at a Saks x Vogue event in New York, she definitely seemed to have marriage on the brain! "I think I feel my most beautiful when I’m happy," Chopra gushed, calling herself a "super" romantic. "I really feel like the best thing a woman can wear is her confidence. Your clothes, your shoes, your bags, all of that is the packaging. But when you have confidence, the world buys whatever you sell."
She continued, "I'm super mushy. When you love someone or when you care about somebody, making them feel special and giving attention is the most important thing. I love the idea of getting married. I totally want to get married at some point."
July 6, 2018: Jonas and Chopra Rock Matching Gold Rings
