Tyga Boycotts Club For Banning Underage Girlfriend Kylie Jenner

Tyga pulled a no-show for a club appearance when the place shot down his demands to get his underage GF Kylie Jenner into the West Hollywood hot spot.

Sources at Greystone Manor say Tyga begged and pleaded with promoters to get 17-year-old Kylie admitted -- calling several times throughout the day. He even pushed his arrival time to 1:30 AM while trying to negotiate Kylie's entry.

When the club wouldn't budge -- y'know, because of the law and stuff -- he bailed.

Tyga pulling out pissed off sponsor, Ciroc, in a big way. The club is trying to reschedule, but since the 21-and-over rule isn't changing ... seems pretty hopeless. So much for love lol...
