Lindsay Lohan’s on-off boyfriend Calum Best has vowed to enter rehab to beat his drink, drugs and sex addictions.

Calum Best, whose sometime lover Lindsay Lohan checked into rehab for the second time on Monday (28.05.07), admits he needs to get help so his life doesn’t spin out of control.

The 26-year-old model – whose soccer legend father George Best died in 2005 aged 59 following a lengthy battle with alcoholism – confessed to Britain’s The Sun newspaper: “I’m a bad boy. I go out and get drunk, I get high on cocaine and I do stupid debauched things with the wrong women.

“When I’m high I do wild stupid shit. I’m a red-blooded male and I’m addicted to sex. I don’t have to be like my dad, but I feel his blood running through my veins. I need to sort out my problems before it’s too late.”

Calum’s frank admission came after pictures were published of him indulging in a cocaine-fuelled threesome with two prostitutes.

Just when you thought it couldn’t get worse for Lindsay Lohan.
