"I date a lot less as a single mom - I'll tell you that. I just don't have time," Lakshmi told reporters at the Elton John AIDS Foundation's 13th Annual Enduring Vision Benefit.

"As you get older, I think it's harder to meet the right person. You just want to be careful because you have a family," she said.
"There's still so much to be done with AIDS, and (Elton) has really been such an early supporter and a consistent supporter," she added.
