Britney Spears and Kevin Federline's Steamy Hotel Rendezvous Revealed

In his forthcoming memoir, "You Thought You Knew," Kevin Federline, now 47 years old, provides a behind-the-scenes look at his relationship with ex-wife Britney Spears, 43. Federline recounts how the two first met in 2004 when he was a backup dancer for the band LFO, which was opening for Spears on her tour. Though they had never properly met before, a mutual friend, Teresa Espinosa, introduced them at a Hollywood nightclub.

Federline, who was 26 at the time, admits he was initially "just thinking about smashing" Spears. However, their encounter quickly blossomed into a whirlwind romance. That same night, Spears invited Federline to join her for a late-night swim at the Beverly Hills Hotel, where she had a private bungalow. The two then retreated to the bungalow, where Spears "turned around, slipped off her underwear and started kissing" Federline.
