Tyga to officially propose Kylie Jenner on her birthday?

Los Angeles, Rapper Tyga will reportedly propose his reality TV star girlfriend, Kylie Jenner, officially on her 19th birthday.

Tyga, 26, said it is difficult to think of a gift for the "Keeping Up With the Kardashians" star, who already has so much in her life, reported People magazine. 

The "Hookah" rapper said he has to see if he can plan a big surprise.

"I don't know. We gotta see. I don't wanna give it (engagement ring) away. "She might be watching, so I can't (say). It's just really about what you feel. How do you get someone that has everything, you know?," he said.

Tyga gifted Jenner a Ferrari on her last birthday, and it seems he may have another big surprise for his girl, who will turn 19 on August 10.
