The singer was previously engaged to comedian Pete Davidson in 2018, however they called off their engagement after five months.

While Grande's relationship with Davidson was highly publicised, the 27-year-old singer has kept her new relationship with Gomez relatively quiet.

Unlike comedian Davidson, who is best known for his role onSaturday Night Live,Gomez works as a luxury real estate agent.

According to Page Six ,the 25-year-old has "previously represented mansions and estates that have sold in a range from $US5 million to $US12 million".

From Matt Damon to Zac Efron, here are 15 other celebrities who have dated or married normal people.

Matt Damon and Luciana Barroso.

In 2003, while filming the movieStuck on You, Matt Damon walked into a bar. He spotted his soon-to-be wife, Luciana Barroso, across the room.

"I was working as a bartender in South Beach (Miami) and he was shooting a movie there and the crew ended up in the bar one Saturday night… Matt’s story is that he saw me across the room and there was a light on me. And I’m like: 'Yeah it was a nightclub - there were lights everywhere!'" Luciana told Vogue in 2018.

"But he had started getting recognised and asked for pictures and autographs, and then it got kind of aggressive because people are drinking and stuff, and so he came and hid behind my bar… [wanting to] just hang out back there and have a drink.

"So I put him to work with me! He had trained as a bartender for a film years before, so he started making drinks. And he made me a ton of money in tips that night, because of course everyone wanted to go and see him. So it turned into a really fun night and then 15 years later here we are!"

Damon and Barroso married in 2005 and have four children.

Eddie Redmayne and Hannah Bagshawe.

Eddie Redmayne met Hannah Bagshawe when he attended Eton College.

"Hannah was at a girls' school near Eton, and they invited some of our guys over to do a fashion show for charity," Redmayne told the Daily Mail UK.

"I saw Hannah across the room at a party afterwards and she was very beautiful and very funny, and she loves the arts and theatre just as I do, so we became friends."

In 2012, Redmayne invited Bagshawe to Florence while he was filmingLes Misérables. And two years later, they married.

These days, Bagshawe works as a PR executive. They have two children together.
