Former "Bachelor" contestant Gia Allemand, 29, was taken to University Hospital in New Orleans Monday night following a "serious emergency medical event," the reality star's rep told ABC News.
She is listed in critical condition.
"Ms. Allemand's mother is with her, along with her long-term boyfriend, NBA Basketball Player Ryan Anderson of the New Orleans Pelicans," the rep added. "On behalf of the family, we kindly ask for privacy at this time. Further statements will be released as more information becomes available."
Jake Pavelka, "The Bachelor" from Allemand's season, tweeted about the incident.
"Please pray for @GiaAllemand… A dear friend and one of the sweetest women I know… #powerofprayer," he posted.
Pavelka and Allemand were part of season 14 of "The Bachelor" in 2010.
