A classic tale of love conquering social divides, "Pretty Woman" remains a beloved rom-com decades after its release.

In reality, DiCaprio and Winslet formed a strong friendship during the making of "Titanic." Even though they've never been a couple, their friendship has endured over the years, leading to another compelling collaboration in "Revolutionary Road" (2008) and that absolutely iconic moment at the 2016 Oscars when DiCaprio finally got the coveted award and Winslet was there cheering for him and tearing up just like the rest of us.

You just put your lips together and blow" – the chemistry between them is electric. A war-time romance set in Martinique, their mutual attraction is palpable throughout the film.
