"It's so irresponsible. We always had our car seat," Camille, 44, told TMZ. "And we had two children [Mason, 11, Jude, 8]."
The Real Housewives of Beverly Hills star divorced Kelsey in February 2011 after 14 years of marriage. Kelsey had been caught having an affair with Kayte, a British flight attendant who is 25 years his junior. They married in February 2011 and welcomed their first child Faith on July 13.
"I just think it's extremely irresponsible," Camille said of her ex's failure to use a car seat. "But hey, he's married to a European girl, maybe they're different in Europe. Maybe it's a European thing."
"I am not an attorney, so I cannot [comment] on any legal aspect. I just know that the original footage that aired strongly implied that they left the airport without a car seat, which was not the case," Grammer's rep, Stan Rosenfield, said.
"In an attempt to avoid the paparazzi, they exited through the upper level," he explained. "Kelsey went back in and got the car seat and met them at the car. Did the car drive a few yards without the car seat? Yes. At no time does the video show them leaving the airport with the baby not in the car seat."
Last month, Grammer's parenting choices also came under fire when he brought his infant daughter to Hugh Hefner's Playboy mansion Halloween party. The actor defended his decision, telling USA Today, "Kayte is breast-feeding and we do not have a nanny or a trusted baby-sitter at this time, so Faith goes everywhere with us."
