Amber Rose "never knew what a true heartache felt like" until Wiz Khalifa split

Breakups can be rough, and Amber Rose is speaking out about the pain she's feeling in the wake of her split from Wiz Khalifa.

The model filed for divorce from the rapper last month after a year of marriage, and soon after denied allegations that she cheated but hinted that Khalifa may have been unfaithful.

On Tuesday, Rose took to Twitter and admitted things have been difficult for her lately.

Rose and Khalifa married in July 2013, a few months after she gave birth to their son, Sebastian. She's asking for full legal and physical custody of the boy, and Khalifa in his own filing asked for joint custody and visitation rights.
