Britney Spears: Sister Jamie Lynn Spears celebrates mom's birthday after hotel incident

Lynne's birthday celebrations appear to have taken place in Los Angeles.  The Daily Mail obtained footage of her arrival at LAX late Friday. Despite paparazzi inquiries, Lynne remained focused on meeting her son Bryan, offering a simple "yes" when asked if she'd always support her daughter Britney.

It's uncertain whether Lynne spent her special day with Britney. This comes after a concerning incident involving the 42-year-old pop star at the Chateau Marmont hotel. Paramedics responded to reports of an altercation between Britney and her boyfriend, Paul Richard Soliz.  Photos depict Britney shielding herself as she exited the hotel with Soliz, while first responders were on the scene.

The Los Angeles Fire Department confirmed responding to a call about an injured female at the hotel, though details remain unclear.  Page Six sources indicate Britney was unharmed and returned home safely.
