Sulli has sparked rumours that she is a lesbian after kissing Goo Hara on the lips. The duo who have been friends for a long time, got close during a live Instagram broadcast, to celebrate Sulli's birthday, which is March 29.

In the video, Sulli and Hara, who are wearing matching dresses, surprised fans after locking lips together. Fans instantly started doubting her sexuality. One fan said: "I think they're lesbians?"

"I'm afraid the two will announce they''re dating in the future.." another fan added.

"It looks like they'll come out bisexual soon," a third fan said.

It was recently revealed that Sulli and Dynamic Duo's Choiza have split. The duo decided to end their relationship after dating since August 2014.

Choiza's label Amoeba Culture revealed the real reason for their split. The note read: "We're very cautious since it's a private matter of our artist but we're speaking up as many are showing concerns. The two people naturally grew apart due to the busy schedules and different ways of life. They will now treasure the time they spent together as good memories, and support each other's future at their own positions as a good colleague and friend."

Meanwhile, the actress' agency SM Entertainment also confirmed the break-up news. The statement read: "Sulli and Choiza broke up. They agreed to maintain a good relationship."
