Gaga has tweeted 4 times, each with 'clues' to the 2012 Worldwide tour.
The second tweet down, opens the Born This Way video on YouTube which is striking rumors that the tour will be called 
'The Manifesto of Mother Monster'
if you listen to the intro of Born This Way, this is the first line Gaga reads - and could be a vital giveaway!
Plus, the stage designs will be revealed on Tuesday (as tweeted).

On 29th January 2010, from the set of Bad Romance video, Gaga tweeted;

and today, two years on in 2012 the #hashtag is still going! So join in and tweet #NationalLadyGagaDay!

Heavy Metal Lover has been added to the 'Born This Way' entry on Wikipedia.

You can see on the picture that Heavy Metal Lover has been entered with a release date of
February 12, 2012

If this is true, this could be Gaga's LAST single from the Born This Way album :(
But as we have already said 'Guidos' is set to be a single from her NEW album!

Here is the BTW Ball Tour Bus! And it's called the 'Highway Unicorn', we have compared it to Gaga's last tour bus from The Monster Ball:

Lady Gaga is insisting that when she comes to the UK in the next few weeks she is fed by her favorite British chef, Angela Farmer.
An inside source said;"Gaga loves Angela, who's lovely, smiley and prepares exquisite meals for her.
"Gaga won't eat anything unless it's been specifically prepared by Angela, which means meal times can be a bit of a nightmare".

Angela farmer works at The Lanesborough Hotel in Knightsbridge, London - which makes us think Gaga will stay there when she visits soon.

SOURCES FROM US RADIO STATIONS SAY
that Lady Gaga's next single from the 
Born This Way album will be Heavy Metal Lover, followed by Bloody Mary and Bad Kids.
Gaga is then expected to release her new album with a song called 'Guidos' after these last 3 single releases. (See article below)

RUMORS SAY THAT RedOne has announced that an electro-dance song named 'Guidos' will be the first on second single on Lady Gaga's next album.
The song would link nicely with the accusations given to Gaga that her male alter-ego, Jo Calderone was a 'guido' - which is slang for an Italian weak boy.
Who knows?! If it's true were in for a TREAT!

Cynthia and Joe Germanotta, Gaga's Mother and Father have opened Italian restaurant 'Joanne' - named after Gaga's grandmother Joanne Germanotta.
