Britney’s Sex Life In Trouble Pop-tart Britney Spears has reportedly become so obsessed with her newborn son, Sean Preston, that her sex life has become non-existent.

The Toxic singer - who touted the virtues of the pregnant sex she had with aspiring rapper Kevin Federline, saying it was "crazy good" - is determined to rekindle the flame with romantic roadtrips.

Early last year, the sexpot told People magazine that sex is: "better than it was before".

According to Asian News International, Spears had reportedly "mastered" the art of giving oral sex thanks to a little help from 'Sex And The City' star Kim Cattrall. Britney reportedly gained this important knowledge on the art of fellatio after reading a sex manual written by Cattrall, 'Satisfaction: The Art of the Female Orgasm'.

The Actress' book contains what has been described as numerous graphic diagrams, complete with instructions on how to perform a variety of sex acts and different positions for intercourse.

According to the makers of a documentary, Britney's redneck Roots, the sexy singer purchased the how-to while dating pop heartthrob Justin Timberlake.

If Britters continues to blow-up, the only way she's going to keep Kevin happy is to become better at 'that' than anyone else on the planet. The federjerk has already been reportedly calling her names and relentlessly teasing her about her weight.
