Jason Derulo may not be so single anymore. It is rumored that he is currently dating Daphne Joy, 50 Cent's ex-girlfriend.

According to TMZ, Derulo met the model and fashion designer while on a trip to the U.K. Joy and 50 Cent have a three-year-old son together.

A source told Us Weekly the pair is "hanging out and seeing where it goes" and that they "started getting cool in London a few week ago." According to the site, the "Talk Dirty to Me" singer recently posted a picture with Joy captioning it #FlashbackFriday #London #Goodtimes and later deleted it.

Last year, Derulo split with girlfriend and American Idol alum, Jordin Sparks. Their three-year relationship did not end so well, as it was rumored that Derulo cheated on Sparks and ended the relationship over the phone.

However, Sparks was the first to move on and is dating rapper Sage the Gemini. She even revealed to Entertainment Tonight she could see herself marrying him and that he calls her "wife."
