Meanwhile, the deejay spun some Jay-Z hits too – and he seemed amused by one particular mashup. Noticeably missing from view: Beyoncé's $5 million wedding ring

at a screening of their new movie, Towelhead
, at the Arclight Cinemas in Hollywood. Bello, who was wearing her engagement ring

Just one day after premiering his film Burn After Reading
at the Toronto Film Festival, director Joel Coen
and wife Frances McDormand
took a casual stroll down Avenue Road, near the Park Hyatt hotel. Dressed down, the couple looked at ease with each other as they chatted and walked arm in arm.
