An onlooker told America's New York Post newspaper: "They made out all night
before going upstairs to the off-limits bedroom area of the house."
Sexy mum Britney - who was alleged to have stolen Kevin from Shar when she
was pregnant with his baby - tied the knot with the dancer-turned-singer in
September 2004, eight months after divorcing Alexander.
Ever since, the pair have been dogged by claims their relationship is on the
rocks.
Last year, the 'Toxic' singer admitted to America's Allure magazine that
married life is tough.
She said: "We hit a little bit of reality - hard core - after the first
three weeks.
"Before we got married we were on tour and we were just like kids ordering
room service, saying 'Let's go out tonight.'
"Then all of a sudden you have this home and you have kids and you have to
get diapers and get the dogs to the vet.
She added: "It's this whole reality, you know?"
