Ah, love!

Some people meet their future spouses in coffee shops.

Others casually bump into their potential soulmates on the street.

Then, there are a few that build connections in their work environments.

It's happened more often than we think, particularly among celebrities!

Many famous couples that everyone obsesses over found love with their costars, during what seemed like just another day, another dollar.

From MKG and Megan Fox to John Legend and Chrissy Teigen – here are a few A-listers who found their happiness on set!

Olivia Wilde and Harry Styles' hot romance definitely took everyone by surprise!

Before these two lovebirds began smooching across the world, the Booksmart director was happily engaged to Jason Sudeikis.

Jason and Olivia share two children, Otis and Daisy, and were together for quite some time. However, the pair "amicably" split in November 2020, with sources explaining that their primary focus would be on their children.

But before anybody had time to fully digest the breakup — Olivia was spotted holding hands with Harry at the singer's manager's wedding in California earlier this year!

Apparently, the two kept their romance a secret while working on the movie Don't Worry, Darling.

From there, the couple seemed to flaunt their PDA around town, while reports of how Jason was handling the situation confused everyone. Some said he was distraught at his ex finding a new, younger man, while others claimed he had moved on himself.

All in all, it seemed that things have worked out for the best. The Horrible Bosses star is currently dating his Ted Lasso co-star Keeley Hazell, who he also ironically met on set!

Meanwhile, Harry and Olivia have continued their sizzling romance and were recently seen making out on a boat in Italy.

While some have voiced opinions about the 10-year age gap between Harry and Olivia, they certainly are proving that age ain't nothing but a number!

Speaking of sizzling, and somewhat bizarre, PDA.

You'd have to be living under a rock if you don't know about Machine Gun Kelly and Megan Fox.

While this was another surprising romance, it certainly has been very entertaining.

Megan and MGK began their relationship after the two met on the set of his music video, Bloody Valentine.

The Transformers star appeared in the video, much to the delight and shock of fans.

However, Megan's newfound happiness has followed her tumultuous split from her longtime hubby, Brian Austin Green.

Megan and Brian also met on set! The two costarred on Hope & Faith when she was just 18-years-old, and he was 30.

The major age-gap didn't sway the former spouses, as they went on to wed and have three boys together.

Yet things haven't always been smooth sailing. Megan filed for divorce from Brian in 2015, but the two reconciled and welcomed their third child together in 2016.

In 2020, the two confirmed their separation and Megan filed for divorce for the second time.

Since their split, the 35-year-old has publicly blasted her ex-husband. However, recently things seem to be more amicable between the two. Especially since they've both moved on.

Anyway, back to MGK: Megan has also been very – and we do mean very – open about her love for the rapper, who is four years her junior.

The two haven't been able to keep their hands off of each other since going public.

Will the Jennifer's Body star remarry?

Time will tell, but in the meantime, we'll be over here jealous that Megan Fox gets to smooch MGK's handsome face. *sigh*

Let's go back a few years for a moment.

Gwen Stefani's marriage to Gavin Rossdale seemed pictured-perfect from the outside looking in.

After meeting in 1995, the two wed in 2002 and went on to have three sons.

Yet in 2015, the No Doubt singer filed for divorce from Gavin.

The split got even more messy when reports swirled that the guitarist had been unfaithful and cheated on Gwen with their nanny. (Seriously, why is it always the nanny?)

In 2016, the Sweet Escape singer did reveal that her breakup from Gavin was "embarrassing," but both have since moved on and amicably co-parent their boys.

Anyhow, fate saw it fit that Gwen would get a second chance at love. The pop star announced in November 2015 that she was dating her The Voice cohost, Blake Shelton.

Blake himself had also had a painful split from his ex-wife, fellow country star Miranda Lambert.

Thus, Blake and Gwen quickly became one of the most popular famous couples to meet on set in recent years.

Despite being plagued with rumors that the two were either expecting a baby or prematurely married — the cohosts had everyone swooning over their relationship.

Then in 2020, to everyone's joy, the country crooner proposed to his longtime sweetheart. The two privately wed at the 45-year-old's ranch in Oklahoma earlier this month.

The ceremony paid homage to both Gwen and Blake's different personalities – showing that opposites truly do attract!

So, let's face facts.

Chrissy Teigen may not be having the best year so far.

However, she has undying love and support from John Legend. And that is enough to be celebrated!

John and Chrissy met while filming his music video for the song Stereo. Four years later, in 2013, the two wed in a magical ceremony held in Como, Italy.

John dedicated the epic love song, All of Me, to his wife — and once again we're swooning!

The spouses have had their share of adversity throughout their marriage. Chrissy shared various times about her struggles with fertility.

However, the couple was blessed with two children, Luna and Miles. In 2020, Chrissy announced that she and John were expecting their third child together, but devastatingly, the supermodel suffered a devastating stillbirth in September.

The loss deeply affected the famous pair, but their dedication to their love remained strong.

Most recently, Chrissy Teigen has faced severe backlash amid bullying allegations.

Yet, the Ordinary People singer has still defended his wife despite the heavy criticism — in short, nobody messes with John's wife!

So yes, maybe every love story doesn't start off like a fairy tale. But perhaps begins with just another day at the office.

And if these famous couples have proven anything, it's that love takes work, but nothing is impossible!
