Rapper Tyga appears to have confirmed his relationship with reality TV star Kylie Jenner on photo-sharing website Instagram.

The 25-year-old rapper posted a photograph of her rumoured girlfriend on Friday along with caption: "Certain things catch your eye, but only few capture the heart."

Jenner, who is currently in London to promote new skincare brand Nip + Fab, also shared some pictures of her similar to one that was shared by Tyga. The images were taken when she visited the London Eye on Friday night. 

The 17-year-old reality star wore an oversized red satin coat over a black long dress with high slit. Wearing dramatic lashes and pink lipstick, she completed her look with a pair of suede thigh-high boots.
