This is one way of getting publicity for your next project!

Geri Halliwell is back in the studio recording her upcoming fourth album, and the former Spice Girl must have really gotten hot belting out the new tunes, because she decided to strip down to her bra and tweet this sexy pic!

Let's home this album is better than her last one! The fiery rehead's Passion peaked at #41 in the U.K. upon its release in 2005.

We wonder if she will have Scary or Sporty Spice make a cameo on her one of the tracks!
