Now that Kylie Jenner is finally legal after turning 18 earlier this month, her boyfriend Tyga, 25, has no problem boasting about how he keeps the youngest of the Kardashian-Jenner clan "stimulated."

On his new mixtape, F-- What They Talkin' Bout,King Gold Chains finally addresses his relationship with Jenner. "They say she young / I shoulda waited / She a big girl, dawg / When she stimulated," he rhymes on "$timulated." We guess age has nothing to do with arousal since Kylie was 17 years old for a majority of their relationship.

In addition to touching on his sex life, the 15-track mixtape also features interludes from late greats Michael Jackson and 2Pac. Unfortunately, the project doesn't feature an appearance from Kylie. However, there is rumors she's in the studio working on her recording debut.

Tyga is helping her write "Tinashe-type music," a source revelaed. Kylie could also be enlisting BFF Pia Mia, who's a singer signed to Interscope Records, for an assist as well as her brother-in-law Kanye West.

Perhaps Kylie will outshine older sister Kim Kardashian, who also caught the singing bug with her 2011 track “Jam (Turn It Up).”
