Former NBA and reality TV star Lamar Odom was "fighting for his life" after he was found unconscious Tuesday at a Nevada brothel, the brothel owner said.

Odom, 35, who is originally from South Jamaica, Queens, was in critical condition Tuesday night, E! News Chief Correspondent Melanie Bromley confirmed.

Odom's paternal grandmother, Florence Odom, who lives in Brooklyn, told NBC News in a phone interview Wednesday, she received news about his hospitalization Wednesday morning but had not gotten any updates since then.

"He's a good guy. I don't understand what happened," Florence Odom, 89, said.

She said her son, Joe Odom, was rushing to be at his son's bedside.

Florence Odom said she has not seen her grandson since he went to his uncle Carl's funeral in March 2014 and said she's "praying to God. I'm asking God to please let him survive."

"Lamar is special. He made himself a name all over the world. And he's just a cutie," she said.

The Nye County Sheriff's Department was called at about 3:15 p.m. to Love Ranch in Crystal, Nevada, about 70 miles outside of Las Vegas for a report of an unresponsive man needing an ambulance, Sheriff Sharon A. Wehrly said in a statement.

Odom, former Los Angeles Laker and member-by-marriage of the Kardashian family, was stabilized and taken to Desert View Hospital in nearby Pahrump, the statement said. Officials then tried to have him airlifted to Las Vegas, but he was too tall for the helicopter that was available and he was driven by ambulance to Sunrise Hospital and Medical Center. Odom is listed on NBA.com as 6 feet 10 inches tall.

The emergency call came from Richard Hunter, media director for Dennis Hof, who owns the Love Ranch and other legal brothels in Nevada, the sheriff's statement said.

Hof said his staff had picked up Odom from a home in Las Vegas on Saturday.

"He just wanted to get away, have a good time and relax," Hof told The Associated Press in a phone interview.

Hof said Odom was "happy, he was sleeping every night," while visiting, but two women went to check on Odom Tuesday afternoon after not hearing from him since early morning, and found him face down and unconscious.

When they turned him on his side at the direction of a 911 operator, Odom started "throwing up all kinds of stuff."

Odom had been in rehab in the past, but Hof said that no illegal drugs were found.

Hof said Odom had been taking herbal Viagra and had drunk part of a bottle of cognac since arriving, but had no knowledge of his use of any other drugs.

"It's incredibly sad," said Hof, who turns 69 on Wednesday. Hof is known for his own onetime reality show, "Cathouse," on HBO.

Odom's hospitalization was first reported by TMZ.

Odom, who won two NBA championships with the Lakers in 2009 and 2010, last played in the NBA in 2013, and saw recent reality TV fame through his marriage to Khloe Kardashian.

Kardashian filed for divorce in 2013, citing irreconcilable differences. The divorce has not yet received final approval from a judge.

The two were married in 2009 in a large ceremony that was taped for the E! network, following a whirlwind engagement that was also filmed.

“Khloe Kardashian is said to be inconsolable,” Bromley said.

The Lakers played an exhibition game in Las Vegas on Tuesday night, losing 107-100 to Sacramento. Kobe Bryant and Metta World Peace are Odom's only remaining teammates on the roster.

World Peace clearly was distraught about Odom's health after the game.

"There's not one word I could say that would make sense," World Peace told reporters, declining further comment.

Bryant left the arena without speaking to reporters.

Odom spent the best years of his career with the Lakers, winning two championship rings and the NBA's Sixth Man of the Year award in 2011.

After seven years in purple and gold, he was crushed in December 2011 when the Lakers attempted to trade him to New Orleans in a multiplayer trade for Chris Paul. He eventually went to Dallas in another deal, but was out of the NBA just two years later.

Some troubles that met Odom before and during his career appeared to worsen after he left the league, and included a no-contest plea to drunken driving shortly before his divorce.

Odom was suspended during the 2000-01 season for violating the NBA's anti-drug policy for the second time in eight months. During the 2010-11 season, a cousin he was close to died and Odom was a passenger in a vehicle involved in an accident in New York that killed a cyclist.

Odom played one season at Rhode Island before being drafted in the first round with the No. 4 overall pick by the Clippers in the 1999 NBA draft.

Born Lamar Joseph Odom on Nov. 6, 1979, in New York City, he was raised by his grandmother after his mother died of cancer when he was 12. His father was a drug addict.

In 2006, Odom's 6-month-old son Jayden died from SIDS while sleeping in his crib in New York.

He has a daughter, Destiny, and a son Lamar Jr., from a previous relationship.
