Actress Amber Rose, who recently filed for divorce from husband and rapper Wiz Khalifa, is heartbroken. She says she feels like "she has lost her best friend" and is feeling "true heartache" for the first time.

Rose shared her feelings with a series of emotional posts on social networking website Twitter Monday, reports dailymail.co.uk.

"The mornings are especially hard. The pain...I wake up every morning feeling like my best friend died...I never knew what a true heartache felt like until now," Rose tweeted.

Rose filed for divorce last month amid reports that Khalifa cheated on her with a pair of twins. The duo started dating in early 2011, before marrying in July 2013.
