Aniston is engaged to marry Justin Theroux but details of her wedding are being kept under wraps.
"I know she's engaged but that's all I know. I'm sure I'll find out about it when it's about to happen... for privacy issues... I honestly don't know anything about it. She doesn't consult me on her plans," Handler said on a US chat show.
There were speculations that the couple, who got engaged in August last year, will tie the knot in Hawaii in the coming weeks.
However, her representative later denied the rumours.
