5:43 PM: X17 photographers catch Sam yelling at photographers as Britney got out of his car crying. Britney retreats into her home hiding behind her dog, tearfully telling the photographers that she was "having a nice time with her dog".

Meanwhile, LAPD officers started arriving at the Summit to harrass the paps following a call about some paparazzi sneaking into the gated community. Officers issued citations to the owners of all cars illegally parked in front of the community, while the Summit security team stepped things up, requiring authorization for anyone wanting to enter onto the Summit's grounds.

8:30 PM: Britney's parents arrive at the Summit to meet with their daughter. Initially, they have some trouble getting in due to the Summit's heightened security measures. Even her father Jamie was even forced to endure an impromptu interview with an InTouch reporter - much to his chagrin!

9:00 PM: Britney emerges from her house and hops into her paparazzi pal Filipe's waiting car to make a quick run to Ralph's. Brit picked up a few items and then got Filipe to take her home.

Unfortunately, Brit must have forgotten something; she ended up returning to the supermarket - where she was accosted by some overzealous fans. The exchange must have rattled Britney; we next saw her heading towards Sunset - where she met up with Adnan and hopped in his car!

1:00 AM: Britney emerges from hiding with her mother, Sam, and Chad Hardcastle for a quick errand to Long's Drug Store. The foursome kept silent as they walked back to their car, declining to answer any questions about the night's events. Everyone then retires for the evening.

So just what might have set off the huge fight? We'll let you know as soon as we find out!
