You may want to duck -- there's a lot of stuff hitting the fan right about now. Osama (Sam) Lutfi is making some major bombshell claims about Britney Spears' alleged drug use in his trial, and they're pretty scary. The entire thing sounds like a subplot of 'Breaking Bad.'

Lutfi's lawyers reportedly began their arguments with allegations of Spears' drug use. TMZ reports that Lutfi's attorney, Joseph Schleimer, told the jury, "She liked to use amphetamines. Most everything that went wrong was because of this drug." Schleimer claimed that Lutfi repeatedly made an attempt to use a "varsity team" to get Spears off drugs, and that when he made an attempt to get Spears and her house clean, that's when the drug-sniffing dog found a baggie of crystal meth.

Schleimer also claimed that BritBrit's dad and current co-conservator, Jamie Spears, punched Lutfi while Lutfi was "employed" by Britney. The Spears' team denies all of those allegations, especially that Lutfi worked for Spears to begin with -- in part, they claim, because if Spears was really as high as a kite all the time, she wouldn't have been considered legally competent to hire Lutfi.

TMZ also reports that Lutfi claimed Spears' shaved head resulted from the starlet panicking over drug testing. She allegedly feared that if she was ordered to take a hair follicle drug test, traces of methamphetamine would show up and she'd lose custody of her two tots, Sean Preston and Jayden James.

Even scarier? Lutfi's lawyer also brought Spears' 5150 psychiatric hold back into the light. If you recall the horrifying night Spears was taken out on a stretcher, Lutfi claims an overdose of amphetamines was to blame -- and that he tried getting Spears to see a psychiatrist as soon as two days before the incident happened.

Interestingly, too, Lutfi claims that he introduced Brit to her current fiancee and co-conservator, Jason Trawick, in 2007. Schleimer also made sure to note that while Lutfi, who Spears' family argues was a drug pusher, had a prescription for Adderall -- an amphetamine -- that he only used it on his own to control his ADD. Lutfi also allegedly warned Spears not to go through with her disastrous 2007 MTV VMA performance of 'Gimme More,' but says she refused to heed his advice.

Spears' team hasn't yet responded to Lutfi's allegations, but we can't wait to hear what they have to say.
