It appears Lamar Odom is having a tough time dealing with the death of his best friend Jamie Sangouthai.

A new report claims the 35-year-old was drinking vodka and taking Xanax on a flight on Monday. He was allegedly traveling from Las Vegas to Los Angeles to attend his late pal’s funeral.

“He told the flight attendant ‘Vodka and Xanax and I should wake up there,’” a source told Radar Online. “And he was talking on the phone and told that person that he took Xanax and took two shots.”

It didn’t stop there — the insider also alleged the NBA free agent was making a ruckus!

“He was singing Sade out loud while he was listening to his headphones and he was all over the place,” they said. “He went to the bathroom three times. He jumped up as soon as the seatbelt light went off and went straight to the bathroom. It was a really bumpy flight and a flight attendant asked if he could make it back to his seat or if he wanted to use their jump seat. He didn’t sit there; he just kept playing with the seat, pushing it up and down and laughing.”

Lamar also allegedly spoke ill of his former family, the Kardashians, stating the show and being married to Khloé Kardashian raked in financial benefits!

“He said he thought it [the show] was sick when it started. Then the paychecks started, and it wasn’t so bad,” the source claims. “He told someone ‘I played for a popular team. We won a bit. And I was married to this woman for a little bit.’”

Jamie died on Sunday of an alleged heroin overdose in LA. He was 37-years-old.
