Listen to Ed Sheeran Radio on iHeartRadio

One of Ed Sheeran's ex-girlfriends is providing some insight into a track off his chart-topping album "Multiply."  Scottish singer-songwriter Nina Nesbitt says she's the subject of Ed's breakup song titled, "Nina." 

In an interview with Daily Record, she says Ed did warn her that he'd be using their relationship for material on his sophomore album.  She says she was made aware that there was a song, but "didn't know it was going on the album." 

Nina adds that she's "not really bothered" by it, explaining that they dated "quite a long time ago" and that it turned out to be "a good song."  

Another breakup song is featured on Ed's new album.  "Don't" is rumored to have been written about fellow British singer Ellie Goulding.
