Grammy Crasher
Banned
From L.A. Live
Beyonce shaking it on stage ... the L.A. Sparks ... the B.E.T awards ... all events Grammy Crasher Vitalii Sediuk won't be seeing in L.A. anytime soon -- because he's been BANNED from L.A. LIVE.

Vitalii -- the prankster who ruined Adele's big moment when he ran on stage during the Grammy Awards this year -- faced up to 6 months in jail for his crime. But according to court docs, he copped a plea deal with prosecutors on June 20th and won't spend a day behind bars.

Instead Vitalii was sentenced to 3 years probation AND banned from L.A. Live -- the entertainment complex where the Grammys (and many other glorious events) are held.

And in case you forgot ... this is the same guy who tried to kiss Will Smith on the red carpet in Moscow and gave Madonna a bouquet of hydrangeas -- her "most loathed" flower.

All we can say is, Madison Square Garden: watch your back.
