Photos: Amber Rose mourns the death of her marriage to Wiz Khalifa...aww

She filed for divorce from husband Wiz Khalifa last month amid reports he had cheated on her with a pair of twins. 

But although Amber Rose seems to be doing her best to move on from her marital woes with a series of nights out with her friends, she has admitted she is heartbroken at the breakdown of the couple's union. 

Taking to her Twitter page on Monday for a series of emotional posts, the 30-year-old model explained she feels like she has lost her best friend and that she is feeling 'true heartache' for the first time. 

Amber wrote: '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.'

Her emotional messages come after her estranged husband stepped out with the pair's young son in Los Angeles on Sunday.  

Arriving home, the We Dem Boyz rapper, 27, scooped little Sebastian - whom he shares with separated wife Amber Rose - up out of his car seat and gave him a big hug. 

Dedicating all his attention to the 20-month-old, Wiz left his assistants grab all their gear out of the back of the car and headed towards their home.

Excited to be in his father's company, the little boy pointed out different things in the garden he wanted his dad to see.

Sucking on a pacifier, the toddler was dressed in a cute ensemble for his father son Sunday Funday, wearing a blue and white stripped polo, grey jeans and little blue converse high tops.
