Reports that the two had spilt emerged last month after Refaeli allegedly grew tired of the Titanic star's reluctance to commit. The couple dismissed the reports by putting on a united front during a Los Angeles shopping spree just a few days later.
However, DiCaprio has again hinted he has split from the Israeli supermodel, by reportedly hitting the town in London claiming he was a single guy.
"There was a queue of ladies trying to get near Leonardo - he even had a special security guard with him, just to keep them at bay," Contactmusic quoted a source as telling The London Paper. "Leonardo was telling people he was definitely single, but he wasn't interested in any of the women trying to get his attention," the source added.
