Los Angeles, February 24 – We never thought they’d show up as promised, but what do we know? Newly-split couple Orlando Bloom and Kate Bosworth both put on smiley faces and came to Global Green’s “Rock the Earth” party. The two arrived separately and maintained a distance, avoiding any awkward situations.

Global Green USA is the American arm of environmental organization Green Cross International, and the pre-Oscar party was to encourage clean energy solutions; guests walked a green carpet and signed a letter to President Bush supporting a “smart climate agenda”. (True, this took place in car-dependent L.A., but hey, that’s where all the stars are during awards season.)

Hiding their gas-guzzlers as they arrived were Salma Hayek, Emmy Rossum, Radha Mitchell, Tate Donovan and Sharon Lawrence. Penelope Cruz didn’t want to pose for photos, claiming she’d just had a lot of dental work done, but we managed to lure her into camera range. (Major dental work three days before the Oscars?)

Tim Robbins got there very early, in order to rehearse with his band; he reprised his Bob Roberts folkie persona for the evening, and brought down the house. Incubus, Perry Farrell and others also performed. Cruz’s squeeze, Matthew McConaughey, didn’t attend, and she left with her buddy Hayek.
