As Khloe Kardashian and her famous family continue to keep vigil by Lamar Odom's bedside, Lance Bass says he's been in contact with Kris Jenner.
On Thursday's episode of The Meredith Vieira Show, Bass gives insight into his most recent conversation with the Keeping Up With the Kardashians matriarch.

"I mean, the family is devastated, of course," Bass said. "This is the only family that Lamar has."
Odom's mother died of colon cancer when he was 12 years old, and his father has long struggled with addiction. Odom's strained relationship with his father was documented on the reality show Khloe & Lamar, which aired for two seasons from 2011 - 2012.
As ET previously reported, Odom's father, Joe, had been seen at Sunrise Hospital in Las Vegas, Nevada, where the former NBA star has been since Wednesday. Odom has been in critical condition after he was found unresponsive at the Love Ranch brothel in Crystal, Nevada, the night before.
A source told ET on Thursday that Odom has had a few encouraging moments, fluttering his eyes and it's believed that at one point he squeezedKim Kardashian's hand. Still, ET is being told that the 35-year-old's kidneys are a top concern and that he has been placed on dialysis.

Though Khloe Kardashian filed for divorce in 2013, the estranged couple remains legally married to this day.
"I know from Kris, Kris loves him so much and she was the one that would just call him so much and stay in touch and make sure that he's OK," Bass said on Thursday. "They knew [Odom] was an addict and they wanted to make sure he was safe.
"There was really nothing they could do and you get to the point, you keep getting told when a family member or friend is going through something like that, sometimes you just have to cut it off and that's what they had to do with him," Bass continued. "It cannot be an easy thing. They are by his side right now, they are in Vegas. It's just a sad situation all around."
