Britney Spears has a mini-meltdown

Britney Spears got into what is assumed to be an argument last night with Sam Lufti. Britney and Sam were pulling up to the gate of her house when Britney jumped out of the car. She appeared to be crying and was clutching her dog London. People reports:

Wearing brown high heels, cutoff shorts and a plaid fedora, Spears then seemed to downplay the incident, saying, “I’m fine. I’m . . . having a nice time with my dog.” (She later hopped into a car with another photographer, Filipe Teixeira, who gave her a lift to Ralph’s supermarket in Studio City, before bringing her home. He and another photographer pal were then invited inside, where they spent the remainder of the night.)

After being out of the picture for a while, Adnan Ghalib appeared was not allowed past the gate. The guards had instructions to keep him out. Adnan showed his fellow paps a text from Sam that claims he is a “manic trigger.” Meanwhile, Britney’s parents showed up at the house:

The family reunion didn’t last long, however – as Spears, clutching a bag, bolted from the mansion, says a source. She hopped into a car with Ghalib and the two sped off.

Their getaway hit a speed bump, however, when their car got a flat tire. (Spears is no stranger to vehicular malfunction.) The two pulled into a Chevron to pump air into the deflated tire, then returned to the Summit house – where mom Lynne, and the two photographers, still waited – at around 11 p.m. (Ghalib left soon afterward.)

TMZ is reporting Britney’s parents, along with Sam Lufti and Alli Sims, are finally having an intervention with Britney so she’ll get mental help. I hear Sam has already threatened to pee on Britney’s grave and feed her to Satan if she doesn’t listen. He’s, uh, not very good at these things.
