Ariana Grande and Pete Davidson are reportedly engaged, a mere few weeks after "sources" told People magazine that the couple was casually dating. 

We decided to read between the timelines - and check up on some other celebrity couples you might be wondering about.

Ariana Grande and Pete Davidson

Status: Engaged

What we know: On June 11, Us Weekly reported that the pop star and Saturday Night Live comedian, both 24, are engaged after just a few weeks of dating. And we mean just a few weeks: People reported on May 21 that the pair were seeing each other, but that it was "very casual."

The couple's relationship became Instagram official, as the kids say, on May 30 when Davidson shared a photo of himself and Grande (both self-professed Harry Potter fans) in Hogwarts-themed sweatshirts and robes. In the comments, Grande teased: "u tryna slytherin," a punny reference to the wizarding school's most ruthless house.

Why we care: Everyone loves a whirlwind Hollywood romance (remember Bennifer?), and this one seems particularly dizzying. According to TMZ, Davidson commissioned Grande's rumored engagement ring in May, and wire photos suggest she may have been wearing it while performing at iHeartRadio's Wango Tango concert on June 2.

David and Victoria Beckham

Status: Married, and (according to a strongly worded statement) staying that way

What we know: Rumours began swirling on social media Friday that the soccer star and the singer turned fashion designer would soon announce their divorce. A spokesperson for the couple hit back in a very British way: "What nonsense. Journalist Chinese whispers and fake news fueled by social media," the rep told People. "There is no impending statement, no divorce!"

Why we care: Thanks to their collective beauty, wealth and success, the Beckhams are iconic in the way that Brangelina was. Infidelity rumors have long dogged the couple, who have been married for almost 19 years. In 2006, the couple settled a defamation lawsuit against the now-defunct tabloid News of the World, which they said falsely claimed their marriage was in trouble.

Elon Musk and Grimes

Status: Dating/bonding over artificial intelligence jokes.

The couple seemed to confirm their relationship when they showed up together at the Met Gala, where Grimes notably wore a Tesla logo on her choker. Musk told reporters it was "date night," and that he had helped design the singer's dress.

A couple days later, Grimes appeared to confirm the relationship when she responded to a fan, who tweeted a cat video playfully mocking the pair, with "accurate."

Why we care: Jalopnik called the pairing "the most bewildering space romance of our time" and that pretty much sums it up.

Priyanka Chopra and Nick Jonas

Status: Dating/meeting the family

What we know: Dating rumours started last year when the Quantico actress, who rose to fame as one of Bollywood's biggest (and highest-paid) stars, appeared on the Met Gala red carpet with the singer in matching Ralph Lauren.

Why we care: A Bollywood star and a grown-up Jonas brother! We're just into it.

Taylor Swift and Joe Alwyn

Status: Dating, but it's delicate. Isn't it? Isn't it?

What we know: After about a year and a half out of the public eye, Taylor Swift returned with a symbolic new album and a new boyfriend - actor Joe Alwyn.

Why we care: In a dispatch last month from the opening night of her latest tour, People noted that Swift - who reportedly pointed to her beau while singing "Gorgeous" - had been "quietly dating" Alwyn for more than a year. Their private relationship is in stark contrast to her very visible past romances.

Gigi Hadid and Zayn Malik

Status: Likely on-again

What we know: After more than two years of dating, the model and former One Direction singer announced their split in March. But the pair has been fueling on-again rumors in the months since with adorable Instagrams and public sightings

Why we care: They look great together and genuinely seem to be in love.

Khloe Kardashian and Tristan Thompson

Status: Still dating

What we know: The couple welcomed their first child in April amid tabloid rumors that Thompson, a basketball player for the Cleveland Cavaliers, had cheated on the reality star with multiple women. Two months later, the pair appears be taking the scandal in stride. Khloe supported her beau during the NBA finals, and People reported that she and Thompson stepped out over the weekend in Cleveland to celebrate a friend's birthday.

Why we care: The youngest Kardashian sister's first marriage ended under sad circumstances and allegations of infidelity, but she seemed to have emerged stronger and more confident. Fans just want to see her happy.

Kanye West and Kim Kardashian

Status: Married, and watching Family Feud every night

What we know: It has been a rough couple of years for Kimye between Kim's harrowing Paris robbery and West's public struggles with mental illness. "Kim Kardashian and Kanye West fought hard for their marriage," one People headline claimed last year. And Kardashian has stood by her man even as he's made some controversial statements in recent weeks.

Why we care: Has anything ever made as much sense as Kimye?

Bella Hadid and The Weeknd

Status: Possibly on-again

What we know: The model and singer, who split in 2016 after dating for a year and a half, have been fueling "are they, aren't they" rumors this year after being spotted kissing at Coachella and, a month later, at the Cannes Film Festival. They were also photographed together earlier this month in Paris.

Why we care: Hadid has said that the breakup was hard for her. And there seemed to be some emotional references to The Weeknd's model ex-girlfriend (as well as Selena Gomez, who he dated after breaking up with Hadid) on his recent EP, "My Dear Melancholy."
