London, Sept 16: It seems that actress Sienna Miller is increasingly getting sick and tired of her hectic filming schedule.
Apparently, the star seemed annoyed because her heavy filming schedule didn’t allow her to attend her former step mum Kelly Hoppen's book launch at Asprey jewellers.
"Sienna can't make it. She so sorry, but she can't get out of filming. She's working until 10pm," the Mirror quoted Sienna’s sister Savannah, as telling interior designer, Kelly.
