Super Bowl 2012: Madonna the gym junkie is back on form as she appears press conference days before performance

Bulging biceps and tiny waist: Gym junkie Madonna is back on form… and with those muscles could be competing in the Super Bowl herself
Says pressure is on to perform well and please fans
Promises 'no wardrobe malfunction'

She's as fastidious with her workouts as she is at keeping herself in the showbiz spotlight.

And just three days ahead of her Super Bowl half time performance and it appears Madonna has been hitting the gym hard in preparation for her performance in front of an expected 100m plus viewers.

The 53-year-old singer will make her singing comeback on Sunday when she takes to the stage during the popular American sporting event, revealing she will give renditions of three old songs and her new track, Give Me All Your Luvin.

The Material Girl singer attended a
press conference today in Indianapolis, admitting she is somewhat
nervous about performing in front of such a large live TV audience.

Madge sported a pinstriped outfit for
the occasion, with her waistcoat revealing her bulging biceps which have
made her synonymous with the gym junkie culture.

Her corset-style top also revealed her
tiny waist. Back in May last year she shocked reporters at the Met Ball
Gala in New York, revealing she felt fat in her stunning blue gown.

While fashion critics agreed she
looked stunning, the Queen of Pop had apparently lost her red carpet
confidence and felt self-conscious in the Stella McCartney-designed
clinging dress.

Just a few years back – before taking a
musical hiatus to direct her first movie, W.E., Madge would workout for
hour and hours every day.

In an interview this week, she claims to have cut down – but still admits to doing 90 minutes of exercise five days a week.

'Mania There is that rumour,' she told Anderson Cooper when he asked if she worked out obsessively.

She went on: 'I don't work out as
much as I used to to tell you the truth, it's been widdelled down to an hour
and a half five days a week. I have four kids, I have five jobs.'

Speaking at today's press conference,
Madonna said it was a dream come true to perform at the Super Bowl
halftime show – but conceded she was feeling pressured by singing in
front of the huge live television audience.

Last year's Super Bowl attracted U.S.
viewers of 111 million people – the largest for a single television
broadcast in the United States.

'This is a Midwesterner girls dream to
be performing at the Super Bowl halftime show,' said Madonna, who was
born in Bay City, Michigan.

'In over 25 years of performing that
I've done, I have never worked so hard or been so scrupulous or
detail-orientated or freaked out as much as I have had maintaining my
sanity and trying to make the most major show at this Super Bowl,' she
added.

Asked if she felt the pressure of the
massive audience, Madonna, who has performed at stadiums around the
world on her global tours, replied simply 'Yes, I do.'

Madonna, whose biggest global live TV
performance was likely Live Aid in 1985, said she would sing three 'old
songs' and her new single 'Give Me All Your Luvin' during the show.

She said she would dedicate her performance to her father.

'I was raised in the Midwest, and he
is the personification of Midwestern values, he gave me the work ethic
that I have, so if I am a hardworking girl who never stops its because
of him.

'Also, I am sure of all the things I have ever done in my life this will be the thing he is most excited about,' she said.

The
half time show has increasingly featured high-profile pop acts, a far
cry from the first Super Bowl in 1967 when college marching bands
entertained the crowd.

Paul McCartney, the Rolling Stones,
U2, Prince, Bruce Springsteen, The Black Eyed Peas and Janet Jackson are
among recent performers.

Jackson's in 2004 was the most controversial as she made headlines worldwide with her infamous 'wardrobe malfunction.'

Justin Timberlake, who was performing
with Jackson, grabbed her costume and tugged at it, exposing her
breast's nipple to millions of TV viewers.

Madonna said all efforts had been made to ensure there would not be a similar episode in her show.
'Great attention to detail has been paid to my wardrobe, there will be no wardrobe malfunction – I promise'.
