John Mayer not serious about Jessica Simpson

Thanks to singer John Mayer, Jessica Simpson has a smile on her face again reports Star Magazine.

But Jessica’s friends are worried that she’s more serious about John than he is about her.

For example, when he went home to spend the recent holidays with his parents in Fairfield, Conn., he never even mentioned his new girlfriend. “Jessica didn’t come up once in conversation,� John’s dad, Richard, tells In Touch exclusively. But Richard insists his son is “very private� about his love life. “We never pry,� he tells In Touch.

In other news, Jessica Simpson was told to stay away from a supermarket because she was distracting customers reports Monster and Critics.

The sexy star can't even go grocery shopping without being followed by paparazzi.

Jessica told Britain's Glamour magazine: "Two weeks ago, I was at Whole Foods and probably about 100 photographers were outside waiting for me.

"The manager gave me his card and said, 'Jessica, I'd appreciate it if you wouldn't come in during store hours. Give me a call and I'll open up early or you can come in after we close. But this is very distracting for all my customers.'

"I looked at him kind of shocked. Then I was just mad, not at him but at the situation. I couldn't even live my normal life anymore."
