Says a source, "It isn't new. He has always been known for his flirtatious behaviour - as a Casanova, in fact. Only recently, he was seen getting cosy with one of his fellow co-star."
The person in question has been linked to almost all his leading ladies in the past. He is also infamous for sending late night messages to his female friends as well as semi-nude pictures of himself, and frequently inviting them over to his place.
"He seems to be thoroughly enjoying his single status," adds an industry insider.
