As if right on cue, Madonna and Guy Ritchie were photographed heading into dinner in London last night. Her rep already denied rumors that the couple is splitting up, but a little arm-in-arm evidence never hurts. Last night they had something to celebrate, too, because she announced her bold new way of releasing Hard Candy. For the week leading up to its April 28 release date, Vodaphone subscribers in Europe will be able to buy one of her songs per day using their mobile phones. Unfortunately, those of us in the US will just have to patiently wait that extra week for our Candy fix.
