The pop superstar will take to the stage for the half-time concert during the big game in Indianapolis, Indiana on Sunday (05Feb12) and she has been hard at work this week (beg30Jan12) putting the final touches to heract.

She reportedly thanked her staff for their dedication on Wednesday by placing a massive order with a local Papa John’s fast food eaterie, askingfor 50 pizzas for all her workers, according to TMZ.com.

The website reports the bill came to more than $500 (?312), but restaurant staff gave the Material Girl a discount.

The 25-year-old singer said that her dad Joe Germanotta likes to ask her to wear more normal clothes.

“I look the same during the day as I do on stage,” the Sun quoted her as saying.

“My father is still like, ‘Can’t you just put this on?’

“Some of it he just can’t handle,” she added.

A rumor that the recently hospitalized actress has died is spreading on Twitter late Friday.

“RIP Demi Moore” became a trending topic, only further fueling speculation.

It is 100% false.

She’s NOT dead.

Moore is struggling with her health at the moment – but very much alive.

It’s bad enough when Twitter and other social media “kill” a random celebrity via random accident, as has been the case dozens of times in recent months.

But to joke about the death of someone who’s obviously going through very real trouble this week seems especially malicious.
