Jaden Smith may have dedicated his new music video to rumoured girlfriend Kylie Jenner but reports suggest the socialite is actually romancing rapper Tyga.

According to TMZ, Jenner and Tyga have been spending a lot of time together over the past few weeks, with a source confirming to the website that they are an item.

[related]The pair were spotted on a 'date' at Japanese restaurant Kabuki in Hollywood on Monday night (October 6), fuelling romance rumours.

However, insiders close to the 25-year old Hip-Hop star were keen to add that while Tyga is dating Jenner, they haven't got "physical".

A source explained that it is partly down to Kylie's age (she's 17!), revealing: "If we even insinuate they are having physical contact he will deny he's dating Kylie…"

Despite his reservations, the pal added to TMZ that the star has admitted to dating her "privately".
