It’s not who you kiss at the start of the year, but who you kiss as the clock strikes midnight that matters. Celebrities, as we all know, are masters of relationship drama, always breaking up, hooking up, reconciling, and filing for divorce. But, in terms of celebrity romance, 2019 has been a very eventful year, with some significant breakups and even more shocking hookups. Consider this: Pete Davidson and Ariana Grande were undoubtedly the most talked-about pair in 2018, but the Saturday Night Live star has been in three high-profile romances this year alone since their divorce. Meanwhile, Miley Cyrus and Liam Hemsworth have rekindled their love after their divorce left fans reeling and binge-watching The Last Song with tubs of ice cream. While it was shocking to find that Zooey was divorcing her spouse Jonathan Pechenik, with whom she has two children, the news that she was dating Property Brothers star was much more so. And the adorable duo hasn’t been shy about their romance, publishing Instagram images, attending his brother J.D.’s wedding together, and openly confessing their love after meeting on set of Carpool Karaoke.
