Looks like Jessica Simpson doesn't mind being labeled "sexual napalm" by ex John Mayer.

Simpson, 29, broke out laughing Wednesday night when TMZ cameras asked her about Mayer's raunchy Playboy comments.

"I have no comment," she said between giggles.

When asked if she'd "knock him out" boxing, Simpson smiled and said, "no" before getting in a car and driving off.

Earlier that day, Simpson (whose reality show premieres next month on VH1), Twittered, "interesting day so far…hmm. at least i am boxing 2-a-days this week."

In the March issue of Playboy, Mayer, 32, said, "That girl is like crack cocaine to me. Sexually it was crazy…Did you ever say, 'I want to quit my life and just f*****' snort you? If you charged me $10,000 to f*** you, I would start selling all my s*** just to keep f****** you.'"

The couple dated for about a year between 2006 and 2007.

At a Nashville concert Wednesday night, Mayer broke down while apologizing for kissing and telling with Simpson, and making racially insensitive remarks.

"In the quest to be clever," he said, "I completely forgot about the people that I love and that love me."
