Veteran rocker Bryan Ferry's son was spotted kissing actress Sienna Miller at the BAFTAs after-show party on Sunday (11FEB07) night, sparking rumours of a romance. Model ISAAC FERRY, 21, and Miller, 25, were openly canoodling at the event at London nightclub Boujis. An insider tells British newspaper the Daily Mirror, "They were holding hands and he was whispering in her ear. There was a lot of chemistry between them. "They moved into the back room that was cordoned off for select BAFTA guests. They were snogging until 4am before coming out and joining the rest of the party." Miller has been single since she split from on/off boyfriend Jude Law in November (06).
