The singer took part in a Twitter webchat last night where she spoke to her followers about her new single 'Hold It Against Me' and forthcoming album 'Femme Fatale'.

When asked if she would get back into acting Spears said: "I would love to be in a Todd Phillips (The Hangover) or Judd Apatow (Knocked Up) movie."

'Femme Fatale', which is Spears' seventh studio album and follow-up to 2008's 'Circus', is due to be released in March.

It includes production from her long-time partners Dr. Luke and Max Martin, as well as Rodney Jerkins, Stargate, Fraser T. Smith and Bloodshy & Avant.

The singer has also been working this week with will.i.am from Black Eyed Peas.
