2019 wasn't exactly the best year for every Hollywood star as some had to learn what tough love meant the hard way.
Having a long-lasting relationship in the show business industry is hard for couples, and experiencing a broken heart as millions of people watch you is even more difficult.
This year, many Hollywood celebrities bid their seemingly perfect relationships goodbye as they embark on a journey into the single world. Here's a list of A-listers who separated in 2019.

ROSIE O'DONNELL AND ELIZABETH ROONEY
After less than a year of being engaged, Rosie O'Donnell ended her relationship with police officer Elizabeth Rooney.
The news came after observations of the host not mentioning her significant other for some time, while the cop deleted her post from October 2018 about their engagement -- and all other photos with the actress.

It seemed all smooth sailing for the couple who was excited about their wedding preparations and talked about having children. The "Rosie O'Donnell Show" star said about having more kids:
"Well, I think I'm done, but you never know with me. There could be a phone call like what happened with Dakota, and you know, here we go. So I don't know."
MEG RYAN AND JOHN MELLENCAMP
On October 30, Meg Ryan and John Mellencamp called off their engagement, hitting a third mark of breaking up since they started dating in 2010.
