Reality TV star Kylie Jenner is not launching a music album with rumoured beau Tyga.

The 17-year-old cleared the air about the rumours by sharing a post on micro-blogging website Twitter on Monday, reports aceshowbiz.com.

"Focusing all my energy on making my new website amazing when it launches. Not making music," Kylie wrote.

Kylie has been rumoured to be preparing her debut album since earlier this year, when a fake artwork suggesting she had a collaboration with rapper Tyga and singer Iggy Azalea called "Forever Real" landed online.
