Kylie Jenner has ''captured the heart'' of Tyga.

The 'Keeping Up with the Kardashians' star has been rumoured to be dating the 'Rack City' hitmaker for some time and the 25-year-old rapper has now apparently confirmed their romance.

Posting a photographer of Kylie, 17, on Instagram, he wrote: ''Certain things capture your eye, but only few capture the heart.''

Tyga has previously admitted he doesn't care what people think of his ''friendship'' with the teenage reality star.

He said: ''Whether if I tell the world that I love her or I don't, it's gonna be me to dictate that, and how I want to keep my friendship and relationship with her.

''I feel like it doesn't matter what the world thinks. If you're around somebody, and you love being around that person, that's all that matters. I don't feel like what anybody could say would change that... how I feel for her as a person... She's just a good person, she's got great energy.''

Though the rapper has refused to confirm their romance directly, he admitted his ''love'' for her will ''continue to grow''.

He added: ''We've got a group of friends, we've been hanging out for the longest... I've been knowing her and her family for six, seven years, so it's all love there, and we're going to continue to grow.''
