IT’S out of this world as far as publicity attempts go.

But that’s nothing new for Lady Gaga whose fashion choices, including a raw meat dress, have become the stuff of legend.

Known for pushing the boundaries, this time she’s gone stratospheric with her latest tour plans.

The Artpop singer hopes to become the first artist to perform in space.

If she beats classical singer Sarah Brightman, who is preparing a similar adventure, and N Sync’s Lance Bass, who had his space dream scuppered over a lack of funds, to it she’ll be beamed back live to the Zero G Colony high-tech musical festival in New Mexico in 2015.

I can only assume she hasn’t watched this week’s – utterly brilliant – film release Gravity or she’d surely be having second thoughts.

But it’s the other passengers I feel sorry for.

Sir Richard Branson’s Virgin Galactic programme launches next year and a list of stars including Ashton Kutcher, Mila Kunis, Justin Bieber and Leonardo DiCaprio are said to have bought seats to fly to space.

Passengers on the crafts will travel 62 miles to the boundary of outer space, experience weightlessness and an incredible view of the curve of the Earth.

But, if Gaga is her usual shocking self, they can hardly go to the bar for a break when they get fed up.

And, as we know from Alien, in space, no-one can hear you scream.

Looking on the bright side, she will have to do a month of preparatory vocal training because of the atmosphere.

This could be a good thing after all.
