WTF! T.I. & TINY GET ARRESTED IN HOLLYWOOD! GETS CAUGHT WITH E PILLS & COULD HAVE BEEN SIPPIN' ON SOME SIZZURP!

Although cops aren't saying which controlled substance they found in the car, there seems to be evidence of Sizzurp ... aka purple drank ... aka codeine syrup.
-- A form of codeine falls under the class of drugs for which T.I. and his wife, Tameka "Tiny" Cottle, were arrested.

-- Codeine is the main ingredient in Sizzurp, which is a growing problem in the South.

-- Sizzurp is typically ingested in styrofoam cups ... it's become a "thing" in the hip-hop community.

Cops won't say specifically which drug they found, though our sources say it's the class of drugs that does indeed include the main ingredient for Sizzurp.

Both T.I. and "Tiny" were booked on felony possession of a controlled substance.



TMZ has learned ... cops originally stopped the Maybach for making an illegal U-turn on Sunset Blvd.

TMZ has obtained photos of rapper T.I. and his wife Tameka "Tiny" Cottle in police custody on Sunset Blvd. last night ... after they were each arrested for allegedly possessing a controlled substance.

T.I. was placed into a squad car with an unknown male.

"Tiny" was taken to a separate squad car -- both were transported to a local Sheriff's station.

As we first reported, cops pulled over T.I.'s ultra-expensive Maybach on Sunset Blvd around 10:18 PM for a traffic violation and then smelled marijuana. During a subsequent search of the vehicle, cops say they found a controlled substance -- we're told it was not cocaine. The class of the controlled substance that was found includes methamphetamines and ecstasy.

Both were booked on felony possession of a controlled substance.
They were released on $10,000 bail.

As we previously reported, T.I. was released from federal prison back in December -- where he served 7 months behind bars for illegally possessing machine guns and silencers.

Law enforcement confirms ... T.I. is still on probation from the gun conviction, which means last night's arrest could qualify as a violation of his probation ... and he could be sent back to prison.

"Tiny" just twittered, "Jus wanted 2say thank u 2every1 dats been leaving encouraging msgs & prayers! We love u guys:-)going 2bed now! So glad 2b n a nice clean bed."
