Lamar Odom Visits Bam Margera At Hospital, Invites Him to Rehab Center

Lamar Odom is serious about getting Bam Margera the desperate help he needs ... stopping in to visit the "Jackass" star while he's in the hospital, and inviting him to Lamar's very own rehab center.

The former NBA star stopped in to see Bam Tuesday with an offer to get him back on the right path -- sources close to Lamar say he's trying to arrange for Bam to get treatment at one of his Odom Wellness Treatment Centers once he's released from his 5150 hold.

We're told Bam was receptive to going to rehab and was very hopeful during their chat ... saying he wants to see his son, Phoenix. Sources say Bam and Lamar hugged it out as the former NBA star told Bam he'd do everything he can to get him treatment.

As we reported, Lamar has opened up 3 drug treatment centers after his own battles with addiction in the past. He's got Gold Bridge Addiction Center in Louisburg, KS, Wavelengths in Huntington Beach, and Project West in San Diego.

TMZ broke the story, LAPD tracked down Bam Sunday to Trejo's Tacos in L.A. -- law enforcement sources told us his erratic speech and behavior, mixed with his recent threat to smoke crack until he dies, was enough to warrant the psych hold.

Lamar also sent Bam a rehab invite in April after Bam turned himself in for allegedly assaulting his brother. At the time, Lamar talked to us about the advice he'd love to pass along to Bam, as well as why his treatment centers could be a huge help.
