Tyga reportedly skipped a nightclub appearance because Kylie Jenner wasn't allowed to attend.

The 25-year-old rapper - real name Michael Nguyen-Stevenson - is said to have ''pulled a no-show'' for a scheduled public appearance at Greystone Manor in West Hollywood, as the club's promoters refused to let him bring the 17-year-old reality TV star along with him because she is four years underage.

A source said the 'Hookah' hitmaker begged and pleaded with the promoters to allow his rumoured girlfriend to attend the event, and even called them personally several times to try to negotiate Kylie's entry.

But the insider told gossip website TMZ.com that the club wouldn't budge so, after initially delaying his appearance, Tyga pulled out of the event entirely, annoying the liquor sponsor.

The hotspot is currently trying to reschedule his appearance.

The pair, who have been spotted on numerous dinner dates together, first sparked speculation they were dating in September when they went to Universal Studios' Halloween Horror Nights in California with a group of friends.

However, Tyga hit out at the rumours at the time, insisting they are ''just friends''.

He tweeted: ''DONT BELIEVE THE RUMORS, BEEN FRIENDS WITH THE FAMILY FOREVER. WE'RE ALL JUST FRIENDS. (sic)''

Tyga has a two-year-old son, King Cairo, from his relationship with former fiancée Blac Chyna, who he split from in August after nearly three years of dating.
