Kate Bosworth and Alexander Skarsgard enjoyed a casual lunch together in LA Thursday.

Heidi Klum modeled an outfit from her own Heidi Klum for New Balance line during a jog in NYC yesterday. She traded her running shoes for blue suede heels to launch the collection at a party that evening. Her new active wear was the focus of last night's episode of Project Runway, which had designers creating looks to be sold with her collection and highlighted some drama between Heidi and last week's winner, Mondo Guerra. Heidi's fashionable life is full of work commitments, though now that she's retired from Victoria's Secret, she'll have more time for interesting projects like the nude video she filmed with husband Seal.

The third party in the movie's love triangle, Tom Hardy, had the day off from filming to spend shopping solo, after his fiancée, Charlotte Riley, joined him over the weekend. Reese's loved ones haven't made the trip up north, but she's already been back home to visit Jim, Ava, and Deacon.
