"They (Kerr and DiCaprio) looked like they were having a great time. They came with a bunch of friends and were overheard talking about going out the night before,” said a source.
The source also says 30-year-old Kerr, who has two-year-old son Flynn with Bloom, was with two girl friends and sat across from DiCaprio, although the two didn't appear to be flirting, despite being linked together in the past.
Other guests at the party included 'Girls' star Zosia Mamet, The Newsroom actress Emily Mortimer and Michael J. Fox.
