Jessica Simpson has been left "embarrassed" after John Mayer said she was "sexual napalm" in bed.

The 29-year-old singer and actress admits the situation left her questioning why men were looking at her when she was out and about.

She said: "My phone has been ringing. It's more embarrassing. I'll walk into a restaurant or something. I'll walk and feel like men are looking at me - but I feel like they're undressing me."

Jessica also claims she thinks 32-year-old Mayer was "stupid" to break up with her in 2007.

Speaking on US TV programme The View, she said: "He did apologise, but I mean, at this point it doesn't really matter. I mean, I only thought he was stupid for breaking up with me."

Earlier this month Jessica admitted she would always care for the 'Gravity' singer, despite his comments to Playboy magazine.

She said: "I will always care about him. I think he's a great person, a great musician, but I was very disappointed by the article."
