Singer Britney Spears has sparked fresh concerns for her well-being after reportedly having another "public breakdown".
According to People magazine, the singer was spotted arguing with her friend Sam Lutfi as they returned from a short drive around Beverly Hills.
The magazine reports that Spears looked "visibly distraught" as she jumped out of the car at her home.
She then reportedly wandered around with her dog London in her arms, before sitting on a pavement, while paparazzi were snapping photographs of her.
Onlookers said that she "looked completely lost" and had tears in her eyes.
But the singer later told the photographers: "I'm fine. I'm... having a nice time with my dog."
The report also claims that Spears' most recent boyfriend Adnan Ghalib was later refused entry to her house.
