Jude Law and Sienna Miller have been ducking and hiding to avoid the paps ever since they got back together last year, but last night they walked the red carpet very much as a loved-up couple. Jude and Sienna joined a host of other stars at the Costume Institute Gala Benefit in New York, and spent much of the night staring into each other’s eyes and pulling goofy grins. They weren’t the only ones, either. Justin Timberlake and Jessica Biel also made a huge show of togetherness at the very same event, with JT looking more attentive towards his girlfriend than we’ve seen publicly in yonks. Cameron Diaz, meanwhile, was busy being pictured leaving Alex Rodriguez’ apartment with a big grin on her face. Aren’t they all so sweet? Awwww *vomits into bucket*
