Actress Olivia Wilde was married to a real life prince before she and Harry Styles reportedly started dating.
The star was previously married to Tao Ruspoli, 44, who is a director, photographer, and also happens to be a low-key Italian prince.
Olivia previously told Women's Health that she met the prince, who is the second son of Prince Alessandro Ruspoli, 9th Prince of Cerveteri and Austrian-American actress Debra Berger, in 2002.
She said that they met through a friend of her family's towards the end of that year and at first she didn't want to date him because he lived on a bus.
Olivia told the publication: "He wanted to introduce me to this Italian guy who made films and lived on a school bus.
"I said, 'Whoa! I don't want to meet a dude who lives on a bus!'"
But while the pair were completely different and worlds apart, Olivia said at the time that they were aligned and "on the same mission".
She told The Observer: "We’re from completely different worlds, but we have the same mission: to bring film and art together with some sort of political activism."
On the same school bus he called home, they eloped six months later after a whirlwind romance.
Olivia was 19-years-old when she made her decision to wed the Italian prince. They divorced in 2011.
The year after the pair split, Olivia confessed that their sex life had dwindled towards the end of their relationship, reportedly saying: "I felt like my vagina died. Turned off. Lights out. And you can lie to your relatives at Christmas dinner and tell them everything on the home front is just peachy. But you cannot lie to your vagina.
The actress also dated actor Jason Sudeikis after meeting him at a finale party of Saturday Night Live in 2011.
They got engaged in 2012 and share two children together, and were together for nine years before splitting.
Jason has been left "devastated" by the rumours that Olivia and Harry are dating, a source told Daily Star.
They said: "They [Harry and Olivia] have been seeing each other for a while under the radar.
"News of Olivia’s break-up with fiancé Jason came only a few weeks ago.
"Sources have told us he is devastated and was blindsided."
Olivia has also previously been linked to Jake Gyllenhaal after the two actors were spotted together, but they never confirmed their romance.
The actress also been rumoured to have dated Bradley Cooper, Ryan Gosling and Justin Timberlake, but this has never been addressed by any of the stars.
It comes as the MailOnline claimed that the pair are dating yesterday after the pair were spotted arriving back at his LA home with luggage after a trip to California on the weekend.
A source told the publication: "Olivia and Harry have become close and the pair have been spending a lot of time together in recent weeks.
"She has been seen visiting his home on several occasions."
Watermelon Sugar singer Harry took over Shia LaBeouf’s role as Florence Pugh's love interest in Don’t Worry Darling, which Olivia is directing, in September last year.
