They were once said to be lovers when they filmed Taiwanese idol series, Hi My Sweetheart, in 2010. 

Dating rumours between Show Luo and Rainie Yang made headlines again recently after the two Taiwanese artistes shot a commercial together. 

Said to be in a four-month-long relationship, rumour has it sparks flew between the two again when they played a couple for the commercial shoot. According to reports, the couple displayed no sign of awkwardness and readily hammed it up for the cameras when the director requested for them to be affectionate. 

Sources revealed the two singers-actors decided to keep their relationship under wraps and away from the media eye due to their "idol" statuses.\ 

After Show and Rainie's turn as an adorable couple in Hi My Sweetheart, they were suspected to be a real-life couple due to their good onscreen and off-camera chemistry. Seen as a publicity stunt by some fans, reps from both artistes denied the claims and emphasised that they are "very close friends". Rainie and Show were romantically linked with different partners a couple of months later.  

Before they became friends and "lovers", the couple had a long-running misunderstanding between them. Rainie's previous relationship with Show buddy's Alien Huang, did not end on a good note and left the former a negative impression on Rainie. The couple resolved their issues and misunderstandings after collaborating in Hi My Sweetheart.

My reaction to this is this- can they just stop spilling rumors?  I know there's some chemistry between Show Luo and Rainie Yang but they have their life to live.
