What was Britney up to this weekend?

BRITNEY SPEARS spent a subdued weekend with her father, according to People magazine.

The mag reports that the embattled pop princess spent the day on Saturday with her father and assistant BRETT at her Beverly Hills home, before going out for a meal with a small group of people at Citrus at Social Hollywood. When a photographer asked her how she was doing, she replied, "Good."

In other Britney news, supermodel and "Project Runway" judge and producer, HEIDI KLUM, offered the pop star a place in her Beverly Hills home during a German TV interview, according to the Associated Press.

Klum reportedly said, "She can call me and come live in our house with us for a couple of months. I would help set her straight." She also expressed her sympathy, saying, "I am sorry when a young person gets thrown so off track. She has, of course, lived an extremely wild life."

If Britney took her up on the offer, she'd be rooming with Klum and her hubby SEAL and their three children.
