Celebrity Big Brother housemate Coolio has been ordered to go to rehab after pleading guilty to drug possession charges.

The rapper – whose real name is Artis Leon Ivey Jr – admitted possessing cocaine in court in Los Angeles, but a further charge of assault was dropped.

He was arrested at Los Angeles airport last March, and was alleged to have grabbed a security worker’s arm to prevent his luggage from being searched.

A judge has ordered the 45-year-old to undergo 18 months of drug rehabilitation treatment.

Coolio, best known for the 90s chart topper Gangsta’s Paradise, finished third in this year’s Celebrity Big Brother despite being a controversial housemate.

He fell out with many of his fellow housemates, including Liberty X singer Michelle Heaton, whom he reduced to tears with some of his scathing remarks. He was also reprimanded by show producers following a furious row with Shameless star Tina Malone.
