But have they gone their separate ways since then?
According to Taiwanese media China Times, actress Lorene Jen the younger sister of S.H.E s Selina Jen was spotted on what seemed like a late-night date with a man who was later revealed to be Boris after some digging by the media.
On Nov 14, Lorene, 32, was seen with her parents heading to the Taipei Pop Music Centre to attend a concert by S.H.E s Ella Chen. After it ended, they travelled to the Nangang district to visit friends.
Close to midnight, a man whom the Taiwanese media later found out was Boris pulled up in a silver Nissan sports car and entered the same building.
